Hi, I have no problem with marian training before(Chinese-English), but recently I changed a larger training corpus ( train.bpe.zh:18G train.bpe.en:20G total 38G), which is always irregular throwing out this error during training. Why? And what should I do to train these corpus normally? Thank you very much. During training, free -h: total used free shared buff/cache available Mem: 125G 53G 2.6G 48M 69G 71G Swap: 3.8G 2.9G 925M

And another question is： when training, I have set --tempdir /media/wangxiuwan/tmp \ and I see the log info: [2019-08-14 15:00:36] [data] Done shuffling 183177554 sentences to temp files

then I check the directory /media/wangxiuwan/tmp, there is nothing. why? I used to think the tempdir is to save temp files, and the required memory is equal to the corpus' size.

It is clear that I have misunderstood. Can you explain to me? Thank you very much.

[emjotde]

Hi, The temporary files are invisible as they get delete as soon as they are opened. That way the still exist but immediately get removed by the OS once the process finishes. That is a relative fail-proof to make sure temporary files are not kept during irregular process termination. The directory is still being used.

I would indeed guess that the error is connected to temporary space, so changing to a different folder would be my suggestion. Also, maybe update to current master of marian-dev. That should be version 1.7.8. There might be better error reporting.

[wangxw1023]

@emjotde Thank you very much. I have update my marian version to marian-dev 1.7.8. And the training is started normally and lasted for 6 hours. If the error "Error reading from file '.'" is thrown out again, then I contact you again.

[emjotde]

Great. I am closing this issue then. Feel free to re-open if you still have problems.

[frankseide]

But do we know where this comes from? Are we failing to detect errors while writing to the temp file? Then that's a bug.

[emjotde]

We changed quite a lot on error reporting, error bits and stream handling between the version that was used and current master. I would suspect a mix of user error like too little temp space and bad reporting behavior in that case of the older Marian version. I would consider this closed unless we get information that there is a bug. The version used was from December last year: v1.7.6 02f4af4 2018-12-12

@emjotde Hi, after 6 hours, the error throwed out again. tempdir: /tmp I think the tempdir's memory is enough. So I am confused. Error reading from file? Is my server's cache insufficient? then if my corpus's size is 38G, when I use "free -h" and "df -h" check my server, how I can assess the memory is OK to complete the training? Thank you very much!

Can we first establish where the “error reading from” comes from? I suspect it is reading a chopped file where the last line does not end in a newline character, and (hopefully) the code keeps reading until it finds a newline. We may need to temporarily change the code to not delete the tmp file, so that we can inspect it.

Then we should establish why the file is truncated. Is the disk full during write, but we don’t catch that, or is it some strange OS-level caching that messes things up (Windows used to cache data written to network and sometimes failed to flush the cache, causing corrupt files; maybe Linux or your version of drivers does some nasty things like this as well).

[wangxw1023]

@frankseide I think what you said is very reasonable. Let me try. Can you tell me where is the code to delete temp files and what change is I need to do? I have search global in marian's code, but I am not sure where to make changes.

[wangxw1023]

@frankseide Maybe you can tell me what is the rule for judging the terminator， how to judge the last line does end in a newline character? I can check my corpus, is there a sentence pair with no terminator?

[frankseide]

The file should end in a LF character, ASCII code 10, hex 0x0a.

[wangxw1023]

@frankseide Thank you very much. And you have said that we may Need to temporarily change the code to not delete the tmp file, so that we can inspect it. I would like to ask you where to change? Is it setting the trainging paramters: --shuffle-in-ram Keep shuffled corpus in RAM, do not write to temp file

[emjotde]

Hi again. Interesting. I have a couple of questions:

• As you said, can you try using --shuffle-in-ram. That will not use the temporary file and if the error does not occur again we have a hint that it is indeed the temporary file.
• Can you post your full compilation command? I cannot understand why your stack trace does not contain function names etc. That should be compiled in by default and would make error diagnosis a bit easier.
• Can you run df -h /tmp before and during training and post the results?

[snukky]

A comment to the first question: the --sqlite option should also skip using temporary files, and use a SQLite DB file for storing and shuffling the data.

[emjotde]

Let's ignore --sqlite for the moment. By default the sqlite database is created also in the temporary folder and it's larger than the raw text. So if there are some weird hidden space problems that might not really help.

[wangxw1023]

@emjotde @snukky Thank you for both of your reply. Currently, I have restarted the training with --shuffle-in-ram. It seems normal for three hours. I'm not sure whether the error would appear again. about emjotde's two other questions:

• compilation command:

mkdir build cd build cmake .. -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-9.2 \ -DOPENSSL_ROOT_DIR=/usr/local/ssl -DOPENSSL_LIBRARIES=/usr/local/ssl/lib \ -DBOOST_ROOT=/media/wangxiuwan/boost_1_65_1 make -j

• df -h /tmp: before and during training is the same.

(base) work@dbcloud-Super-Server:~$ df -h /tmp Filesystem Size Used Avail Use% Mounted on /dev/sda3 3.5T 2.5T 822G 76% /

[emjotde]

OK, this is a lot of space. So it should not be a space problem. Can you please add -DCMAKE_BUILD_TYPE=Release to your cmake command like this:

cmake .. -DCMAKE_BUILD_TYPE=Release -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-9.2 
-DOPENSSL_ROOT_DIR=/usr/local/ssl -DOPENSSL_LIBRARIES=/usr/local/ssl/lib 
-DBOOST_ROOT=/media/wangxiuwan/boost_1_65_1

We made this the default yesterday, but you might not have that version yet. This will compile with function names and the stack trace should be more informative.

[kpu]

In any case, no space should have triggered ENOSPC on write, assuming proper error checking.

[emjotde]

"assuming proper error checking", well, that's a strong assumption :)

[emjotde]

One bug is that we do not set the file path in the input stream when handing in a temporary file. That at least explains why the error message is saying '.' (default Pathie path) instead of a proper temporary filename from tempnam. So this seems to make Frank's ideas more likely.

[emjotde]

I'll add an option later today to keep temporary files and fix the name issue. Will let you when it's ready to try.

[emjotde]

Branch tempfile now has an option --keep-temp which will keep the temporary files inside the folder instead of unlinking. I also fixed the name handling, so the error should tell you now which of the temporary files failed. We should probably also add a line counter and add it to the error message.

[wangxw1023]

@emjotde Hi, until now, the training is still going on and no error is reported. It seems that the error is really related to temp files. When the training is completed, I will try the cmake method (add -DCMAKE_BUILD_TYPE=Release) and Branch tempfile, and I will post the result.

[wangxw1023]

Hi, the training is still going on. But I think it's a bit strange，Why did the training just arrive at epoch 2, and bleu won't rise? I plan to train for 7 days, but this is only two days. Can you give me some advice on the reasons?

train.log

[emjotde]

Looks quite normal to me. That's a lot of iterations, I would not expect the score to improve. Do you have reason do believe that the results are bad?

[wangxw1023]

@emjotde Hi, emjotde I fell so sorry to tell you that as our server hard drive was broken some time ago, and we lost a lot of corpus, including this issues's related corpus. So branch tempfile's work only can started until we generate the corpus again, which may take a long time. When there is a result, I will upload it.

And about the train log, we both trained the transformer model with marian and tensor2tensor, which used the same corpus. However, the max bleu of marian is 32 while the max bleu of tensor2tensor is 41. Then I believe the training results of marian are bad.

The following is the training curve of tensor2tensor.

[emjotde]

Closing this now due to inactivity (ours). Feel free to reopen. Usually we do not have problems to match T2T performance, no idea where that would come from. On the other hand there were a few bugs in the marian-dev code around that time. Maybe that has solved itself.
