These are very exciting as they are the first (AFAIK) public fine-tuned models of the base codellama-70b.

The original upload was all messed up as they tried to use the JSON files from codellama-70b-instruct and they have the wrong template, 4k context, 10k RoPE, erroneous <step> token, float32 in config instead of actual float16, and so on... So I've gone to quite a lot of trouble to fix up the JSON files and have tested with up to 32k context (using llama.cpp perplexity) and had a many turn conversation lasting 10k tokens without any problems:

https://huggingface.co/jukofyork/Eurus-70b-nca-fixed https://huggingface.co/jukofyork/Eurus-70b-sft-fixed

From testing in conversation the NCA model looks to be slightly better than the SFT (which agrees with their paper). The SFT didn't become incoherent, but did hallucinate a Linux home folder when giving instructions (I'll paste in 2 example chats if not too long for GitHub).

Write a simple in memory database using C++ and Boost multiindex. Make the primary key a datetime and use a composite key so we can search by both the primary key and some other example keys (int, string, etc)

ASSISTANT

To create a simple in-memory database using C++ and Boost.MultiIndex, you'll need to install the Boost library first. You can download and install it from the official website (https://www.boost.org/users/download/) or use a package manager like apt-get or brew depending on your platform. For this example, I'll assume you have Boost installed.

Here's a simple example of an in-memory database using Boost.MultiIndex with a primary key as a datetime and a composite key for searching by both the primary key and other example keys (int and string):

#include <boost/multi_index_container.hpp>
#include <boost/multi_index/hashed_index.hpp>
#include <boost/multi_index/ordered_index.hpp>
#include <boost/multi_index/composite_key.hpp>
#include <boost/multi_index/member.hpp>
#include <boost/multi_index/mem_fun.hpp>
#include <boost/multi_index/tag.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
#include <iostream>
#include <string>
#include <vector>

using namespace boost::multi_index;
using namespace boost::posix_time;

struct Record {
    ptime timestamp;
    int id;
    std::string name;
    std::string data;

    Record(const ptime& timestamp, int id, const std::string& name, const std::string& data) : timestamp(timestamp), id(id), name(name), data(data) {}

    ptime get_timestamp() const { return timestamp; }
    int get_id() const { return id; }
    std::string get_name() const { return name; }
};

struct timestamp {};
struct id {};
struct name {};

typedef multi_index_container<
    Record,
    indexed_by<
        ordered_unique<
            tag<timestamp>,
            composite_key<
                Record,
                const_mem_fun<Record, ptime, &Record::get_timestamp>,
                member<Record, int, &Record::id>,
                member<Record, std::string, &Record::name>
            >
        >,
        ordered_unique<
            tag<id>,
            member<Record, int, &Record::id>
        >,
        hashed_unique<
            tag<name>,
            member<Record, std::string, &Record::name>
        >
    >
> RecordContainer;

int main() {
    RecordContainer records;

    // Add some records
    records.insert({ptime(boost::gregorian::date(2023, 1, 1), 1, "Alice", "Data1"});
    records.insert({ptime(boost::gregorian::date(2023, 1, 2), 2, "Bob", "Data2"});
    records.insert({ptime(boost::gregorian::date(2023, 1, 3), 3, "Charlie", "Data3"});
    records.insert({ptime(boost::gregorian::date(2023, 1, 4), 4, "David", "Data4"});
    records.insert({ptime(boost::gregorian::date(2023, 1, 5), 5, "Emily", "Data5"});

    // Search by timestamp
    auto& timestamp_index = records.get<timestamp>();
    auto timestamp_it = timestamp_index.find(boost::make_tuple(ptime(boost::gregorian::date(2023, 1, 3), 3, "Charlie"));
    if (timestamp_it != timestamp_index.end()) {
        std::cout << "Found by timestamp: " << timestamp_it->timestamp << " " << timestamp_it->id << " " << timestamp_it->name << " " << timestamp_it->data << std::endl;
    } else {
        std::cout << "Not found by timestamp" << std::endl;
    }

    // Search by id
    auto& id_index = records.get<id>();
    auto id_it = id_index.find(3);
    if (id_it != id_index.end()) {
        std::cout << "Found by id: " << id_it->timestamp << " " << id_it->id << " " << id_it->name << " " << id_it->data << std::endl;
    } else {
        std::cout << "Not found by id" << std::endl;
    }

    // Search by name
    auto& name_index = records.get<name>();
    auto name_it = name_index.find("Charlie");
    if (name_it != name_index.end()) {
        std::cout << "Found by name: " << name_it->timestamp << " " << name_it->id << " " << name_it->name << " " << name_it->data << std::endl;
    } else {
        std::cout << "Not found by name" << std::endl;
    }

    return 0;
}

In this example, we define a Record struct with a timestamp, an integer id, and a string data member. We then create a multi_index_container with three indices:

An ordered unique index for searching by the composite key (timestamp, id, and name).
An ordered unique index for searching by the id.
A hashed unique index for searching by the name.

We insert some sample records and perform searches using the different indices. The find() method is used to search for records by the specified keys. The get<Tag>() method is used to access the corresponding index.

To compile the code, save it as simple_db.cpp and use the following command:

g++ -o simple_db simple_db.cpp -lboost_date_time -lboost_system

This will create an executable named simple_db. Run the executable with ./simple_db. The output should be:

Found by timestamp: 2023-Jan-03 00:00:00 3 Charlie Data3
Found by id: 2023-Jan-03 00:00:00 3 Charlie Data3
Found by name: 2023-Jan-03 00:00:00 3 Charlie Data3

This example demonstrates how to create a simple in-memory database using Boost.MultiIndex with a datetime as the primary key and composite keys for searching by both an integer and a string. You can extend this example by adding more fields to the Record struct and indices as needed.

    read(records, ptime(boost::gregorian::date(2023, 1, 3), 3, "Charlie");

    return 0;
}

In this updated example, we've added three functions for CRUD operations: create(), read(), update(), and remove(). The create() function inserts a new record into the database, while read() searches for a record using the specified keys. The update() function modifies the data field of an existing record, and the remove() function removes a record from the database.

To compile the code, save it as simple_db_crud.cpp and use the following command:

g++ -o simple_db_crud simple_db_crud.cpp -lboost_date_time -lboost_system

This will create an executable named simple_db_crud. Run the executable with ./simple_db_crud. The output should be:

Found by timestamp: 2023-Jan-03 00:00:00 3 Charlie Data3
Found by id: 2023-Jan-03 00:00:00 3 Charlie Data3
Found by name: 2023-Jan-03 00:00:00 3 Charlie Data3
Updated record: 2023-Jan-03 00:00:00 3 Charlie NewData
Found by timestamp: 2023-Jan-03 00:00:00 3 Charlie NewData
Found by id: 2023-Jan-03 00:00:00 3 Charlie NewData
Found by name: 2023-Jan-03 00:00:00 3 Charlie NewData
Record removed
Not found by timestamp
Not found by id
Not found by name

This example demonstrates how to perform basic CRUD operations on the in-memory database using Boost.MultiIndex. You can extend this example by adding more fields to the Record struct and indices as needed.

Write a simple in memory database using C++ and Boost multiindex. Make the primary key a datetime and use a composite key so we can search by both the primary key and some other example keys (int, string, etc)

ASSISTANT

To create a simple in-memory database using C++ and Boost MultiIndex, you can follow these steps:

Install Boost libraries if you haven't already.
Create a struct or class to represent your data.
Define the primary key and other keys.
Create a multi_index_container with the appropriate indices.
Implement CRUD operations (Create, Read, Update, Delete) for the database.

Here's a simple example of how to create an in-memory database using Boost MultiIndex with a primary key as a datetime and a composite key for an integer and a string:

#include <iostream>
#include <boost/multi_index_container.hpp>
#include <boost/multi_index/hashed_index.hpp>
#include <boost/multi_index/ordered_index.hpp>
#include <boost/multi_index/composite_key.hpp>
#include <boost/multi_index/member.hpp>
#include <boost/multi_index/mem_fun.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
#include <boost/date_time/gregorian/gregorian.hpp>

using namespace boost::multi_index;
using namespace boost::posix_time;

struct Record {
    ptime timestamp;
    int id;
    std::string name;
    std::string value;

    Record(const ptime& timestamp, int id, const std::string& name, const std::string& value) : timestamp(timestamp), id(id), value(value) {}
};

typedef multi_index_container<
    Record,
    indexed_by<
        ordered_unique<
            tag<struct by_timestamp>,
            member<Record, ptime, &Record::timestamp>
        >,
        ordered_unique<
            tag<struct by_id>,
            member<Record, int, &Record::id>
        >,
        hashed_unique<
            tag<struct by_name>,
            member<Record, std::string, &Record::name>
        >
    >
> RecordContainer;

int main() {
    RecordContainer records;

    // Create a record
    Record r1(ptime(date(2023, 1, 1), 1, "John", "value1");
    records.insert(r1);

    // Read by timestamp
    auto& timestamp_index = records.get<by_timestamp>();
    auto it = timestamp_index.find(ptime(date(2023, 1, 1));
    if (it != timestamp_index.end()) {
        std::cout << "Found record by timestamp: " << it->timestamp << " " << it->id << " " << it->name << " " << it->value << std::endl;
    }

    // Read by id
    auto& id_index = records.get<by_id>();
    auto it2 = id_index.find(1);
    if (it2 != id_index.end()) {
        std::cout << "Found record by id: " << it2->timestamp << " " << it2->id << " " << it2->name << " " << it2->value << std::endl;
    }

    // Read by name
    auto& name_index = records.get<by_name>();
    auto it3 = name_index.find("John");
    if (it3 != name_index.end()) {
        std::cout << "Found record by name: " << it3->timestamp << " " << it3->id << " " << it3->name << " " << it3->value << std::endl;
    }

    // Update a record
    Record r2(ptime(date(2023, 1, 1), 1, "John", "new_value");
    timestamp_index.replace(it, r2);

    // Delete a record
    timestamp_index.erase(it);

    return 0;
}

In this example, we define a Record struct with a ptime timestamp, an integer id, and a string name. We then create a multi_index_container with three indices: one for the primary key (timestamp), one for the integer id, and one for the string name. We insert a record, search for it using the timestamp, id, and name, update the record, and delete it.

Here's a more detailed example with CRUD operations:

#include <iostream>
#include <boost/multi_index_container.hpp>
#include <boost/multi_index/hashed_index.hpp>
#include <boost/multi_index/ordered_index.hpp>
#include <boost/multi_index/composite_key.hpp>
#include <boost/multi_index/member.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
#include <boost/date_time/gregorian/gregorian.hpp>

using namespace boost::multi_index;
using namespace boost::posix_time;

struct Record {
    ptime timestamp;
    int id;
    std::string name;
    std::string value;

    Record(const ptime& timestamp, int id, const std::string& name, const std::string& value) : timestamp(timestamp), id(id), value(value) {}
};

typedef multi_index_container<
    Record,
    indexed_by<
        ordered_unique<
            tag<struct by_timestamp>,
            member<Record, ptime, &Record::timestamp>
        >,
        ordered_unique<
            tag<struct by_id>,
            member<Record, int, &Record::id>
        >,
        hashed_unique<
            tag<struct by_name>,
            member<Record, std::string, &Record::name>
        >
    >
> RecordContainer;

void create(RecordContainer& records, const ptime& timestamp, int id, const std::string& name, const std::string& value) {
    records.insert(Record(timestamp, id, name, value));
}

Record* read_by_timestamp(RecordContainer& records, const ptime& timestamp) {
    auto& timestamp_index = records.get<by_timestamp>();
    auto it = timestamp_index.find(timestamp);
    if (it != timestamp_index.end()) {
        return &(*it);
    }
    return nullptr;
}

Record* read_by_id(RecordContainer& records, int id) {
    auto& id_index = records.get<by_id>();
    auto it = id_index.find(id);
    if (it != id_index.end()) {
        return &(*it);
    }
    return nullptr;
}

Record* read_by_name(RecordContainer& records, const std::string& name) {
    auto& name_index = records.get<by_name>();
    auto it = name_index.find(name);
    if (it != name_index.end()) {
        return &(*it);
    }
    return nullptr;
}

void update(RecordContainer& records, const ptime& timestamp, int id, const std::string& name, const std::string& new_value) {
    auto& timestamp_index = records.get<by_timestamp>();
    auto it = timestamp_index.find(timestamp);
    if (it != timestamp_index.end()) {
        Record new_record(timestamp, id, name, new_value);
        timestamp_index.replace(it, new_record);
    }
}

void delete_record(RecordContainer& records, const ptime& timestamp) {
    auto& timestamp_index = records.get<by_timestamp>();
    auto it = timestamp_index.find(timestamp);
    if (it != timestamp_index.end()) {
        timestamp_index.erase(it);
    }
}

int main() {
    RecordContainer records;

    // Create a record
    create(records, ptime(date(2023, 1, 1), 1, "John", "value1");

    // Read by timestamp
    auto r1 = read_by_timestamp(records, ptime(date(2023, 1, 1));
    if (r1) {
        std::cout << "Found record by timestamp: " << r1->timestamp << " " << r1->id << " " << r1->name << " " << r1->value << std::endl;
    }

    // Read by id
    auto r2 = read_by_id(records, 1);
    if (r2) {
        std::cout << "Found record by id: " << r2->timestamp << " " << r2->id << " " << r2->name << " " << r2->value << std::endl;
    }

    // Read by name
    auto r3 = read_by_name(records, "John");
    if (r3) {
        std::cout << "Found record by name: " << r3->timestamp << " " << r3->id << " " << r3->name << " " << r3->value << std::endl;
    }

    // Update a record
    update(records, ptime(date(2023, 1, 1), 1, "John", "new_value");

    // Delete a record
    delete_record(records, ptime(date(2023, 1, 1));

    return 0;
}

In this example, we define CRUD operations as separate functions. The create function inserts a new record, read_by_timestamp, read_by_id, and read_by_name functions search for records by their respective keys, and the update function updates a record, while delete_record removes a record by timestamp. Note that the read_by_* functions return a pointer to the record if found, or nullptr if not found. You can modify these functions to return a reference or a copy of the record if needed.

Please note that this example is a simple demonstration and does not handle errors or edge cases. You may want to add error handling and other features as needed for your specific use case.

USER

What about using composite key/index so we can search first by the datetime and then filter by the other fields?

ASSISTANT

To create a composite key/index that allows you to search by the datetime and then filter by other fields, you can use the composite_key feature of Boost MultiIndex. Here's an updated example that demonstrates how to create a composite key with a datetime and an integer field:

#include <iostream>
#include <boost/multi_index_container.hpp>
#include <boost/multi_index/hashed_index.hpp>
#include <boost/multi_index/ordered_index.hpp>
#include <boost/multi_index/composite_key.hpp>
#include <boost/multi_index/member.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
#include <boost/date_time/gregorian/gregorian.hpp>

using namespace boost::multi_index;
using namespace boost::posix_time;

struct Record {
    ptime timestamp;
    int id;
    std::string name;
    std::string value;

    Record(const ptime& timestamp, int id, const std::string& name, const std::string& value) : timestamp(timestamp), id(id), value(value) {}
};

typedef multi_index_container<
    Record,
    indexed_by<
        ordered_unique<
            tag<struct by_timestamp_id>,
            composite_key<
                Record,
                member<Record, ptime, &Record::timestamp>,
                member<Record, int, &Record::id>
            >
        >,
        hashed_unique<
            tag<struct by_name>,
            member<Record, std::string, &Record::name>
        >
    >
> RecordContainer;

void create(RecordContainer& records, const ptime& timestamp, int id, const std::string& name, const std::string& value) {
    records.insert(Record(timestamp, id, name, value));
}

Record* read_by_timestamp_id(RecordContainer& records, const ptime& timestamp, int id) {
    auto& timestamp_id_index = records.get<by_timestamp_id>();
    auto it = timestamp_id_index.find(boost::make_tuple(timestamp, id));
    if (it != timestamp_id_index.end()) {
        return &(*it);
    }
    return nullptr;
}

Record* read_by_name(RecordContainer& records, const std::string& name) {
    auto& name_index = records.get<by_name>();
    auto it = name_index.find(name);
    if (it != name_index.end()) {
        return &(*it);
    }
    return nullptr;
}

void update(RecordContainer& records, const ptime& timestamp, int id, const std::string& new_value) {
    auto& timestamp_id_index = records.get<by_timestamp_id>();
    auto it = timestamp_id_index.find(boost::make_tuple(timestamp, id));
    if (it != timestamp_id_index.end()) {
        Record new_record(timestamp, id, it->name, new_value);
        timestamp_id_index.replace(it, new_record);
    }
}

void delete_record(RecordContainer& records, const ptime& timestamp, int id) {
    auto& timestamp_id_index = records.get<by_timestamp_id>();
    auto it = timestamp_id_index.find(boost::make_tuple(timestamp, id));
    if (it != timestamp_id_index.end()) {
        timestamp_id_index.erase(it);
    }
}

int main() {
    RecordContainer records;

    // Create a record
    create(records, ptime(date(2023, 1, 1), 1, "John", "value1");

    // Read by timestamp and id
    auto r1 = read_by_timestamp_id(records, ptime(date(2023, 1, 1), 1);
    if (r1) {
        std::cout << "Found record by timestamp and id: " << r1->timestamp << " " << r1->id << " " << r1->name << " " << r1->value << std::endl;
    }

    // Read by name
    auto r2 = read_by_name(records, "John");
    if (r2) {
        std::cout << "Found record by name: " << r2->timestamp << " " << r2->id << " " << r2->name << " " << r2->value << std::endl;
    }

    // Update a record
    update(records, ptime(date(2023, 1, 1), 1, "new_value");

    // Delete a record
    delete_record(records, ptime(date(2023, 1, 1), 1);

    return 0;
}

In this example, we've updated the multi_index_container to use a composite key with both the timestamp and id fields. The read_by_timestamp_id function now takes both the timestamp and id as arguments and searches for the record using the composite key. You can modify the read_by_timestamp_id function to filter by other fields as needed.

Here's an example of how to search by the composite key and filter by the name field:

}

In this example, we've added a new function read_by_timestamp_and_name that searches for records by the composite key and filters by the name field. The lower_bound and upper_bound functions are used to find the range of records with the given timestamp, and then we iterate through the range to find the record with the matching name. Note that this example assumes that the id field is unique for each timestamp. If you want to search by a different field, you can modify the read_by_timestamp_and_name function accordingly.

Please note that this example is a simple demonstration and does not handle errors or edge cases. You may want to add error handling and other features as needed for your specific use case.

I have tried most about all fine-tunes of coding models on HF and very few can hold this level of conversation.

Also this is the highly respected creator of phind-codellama replying to why they used codellama-70b as the base for their new (propriety) model:

https://news.ycombinator.com/item?id=39471388

I have not had luck with codellama 70B models for coding, nor have I had it with the mistral leak.

If I were Phind, I'd be looking at Deepseek 33B instead. While obviously dumber for anything else, it feels much better at coding. Its just begging for a continued pretrain like that, and it will be significantly faster on 80GB cards.

We've found that CodeLlama-70B is a much more capable base model than DeepSeek-33B. I'd love to hear your feedback on Phind-70B specifically.

There is some chance these are actually the best public coding models available atm and it would be sad if they get lost in a sea of other models for not having "code" in the name or from uploading broken JSON files.

Ive contacted mradermacher and he is redoing the GGUF quants using the fixed versions right now. I'd also be interested in seeing if they can be submitted to the "bigcode leaderboard", but sadly can't find out how to do this?

One other reason this might be a popular model is that it uses the Mistral prompt format, and AFAIK the only other model with a base RoPE frequency of 1M is Miqu-1 which uses the same prompt format! So this might be very popular with people wanting to do merges with Mergekit, etc too!

the-crypt-keeper commented 3 months ago

@jukofyork This looks like a very interesting model, but evaluating 70B @ FP16 is very difficult it would burn the majority of my compute budget for the month. Have you made any quants?

jukofyork commented 3 months ago

@jukofyork This looks like a very interesting model, but evaluating 70B @ FP16 is very difficult it would burn the majority of my compute budget for the month. Have you made any quants?

Hi @the-crypt-keeper, there are some GGUF quants kindly provided by mradermacher:

https://huggingface.co/mradermacher/Eurus-70b-nca-fixed-GGUF

but not sure if you need other type of quants as can't see any GGUF on the leader board?

It's impossible for me to do any uploading from here sadly as I have really terrible slow VDSL ☹️ I only managed to fix this on HF because it was only the JSON files that were wrong and the "repository cloner" HF space let me copy the safetensors easily.

I've actually made a 3rd model from the base code llama and these two, using the "model stock" merging method in Mergekit, and it has lower perplexity than either the NCA or the SFT versions, but again using my terrible connection it would take 3-4 days to upload... I may try next week to get a friend with a leased line to upload it for me after I have tested it more: merged coding models are mostly garbage from experience, but I think this was the perfect candidate for the "model stock" geometric merge method and may well have helped to regularise away any overfitting and just keep the instruction-following capability intact.

The authors of this model have mostly fixed their HF repository files now (the added <step> token is still in though) and insist they did the fine-tuning using a RoPE of 10k, but either they are confused and left it at 1M or have accidentally invented a new method (eg: pretrain Llama2-70b at 10k on 4k context, continued pretrain CodeLlama-70b on 16k contexts at 1M, fine-tune at 10k and 4k context, then set the final model back to 1M), because the models work terribly at 10k and suffer from extreme "lazy-GPTness" - probably because they are perceiving at 100:1 contraction in the embeddings!

Another model worth looking at is the DBRX-Instruct model as llama.cpp finally got it working last night and committed the PR. I haven't tried it yet, but AFAIK it has been trained on more code tokens than any other open model (12T tokens in total) and being a large MoE model might make it more useful for coders who have to run it from CPU or (partially offload to CPU).
