from chatterbot.corpus import load_corpus, list_corpus_files ImportError: cannot import name 'load_corpus'

[aspiringguru]

I'm sure I've had this basic example of chatterbot corpus working previously. Following examples from https://chatterbot.readthedocs.io/en/latest/training.html#training-with-corpus-data and https://chatterbot.readthedocs.io/en/stable/corpus.html

I'm experiencing this error.

from chatterbot.corpus import load_corpus, list_corpus_files ImportError: cannot import name 'load_corpus'

full code below. Have replicated the problem on Windows10 and Ubuntu 16.

I'm sure this is a simple and obvious problem, but really throwing me atm.

environment: Windows 10 $ python --version Python 3.6.5 :: Anaconda, Inc.

$ pip freeze | grep chatterbot chatterbot-corpus==1.2.0

same problem on AWS ubuntu 16 (using python Python 3.6.7 & chatterbot chatterbot-corpus==1.2.0)

@aspiringguru, It is possible that you are using an older version of chatterbot. I see that the chatterbot-corpus version you are using is 1.2. You'll want to make sure you have chatterbot 1.0 downloaded or installed for this to work.

[aspiringguru]

This was a fresh install of chatterbot yesterday. also: my bad, just noticed I only listed the chatterbot-corpus version.

$ pip freeze | grep atter ChatterBot==1.0.2 chatterbot-corpus==1.2.0

also checked with pip install --upgrade ChatterBot pip install --upgrade chatterbot-corpus same version after update as above.

also, checking my python runtime is not somehow using a different environment. import chatterbot print(chatterbot.version)

1.0.2

I'm was not able to check version of chatterbot-corpus programmatically inside runtime.

I've seen other questions/answers about corpus paths - when creating custom corpus.

I can see chatterbot corpus files in C:\Users\blah\Anaconda3\Lib\site-packages\chatterbot_corpus\data

other directories I can see installed C:\Users\blah\Anaconda3\Lib\site-packages\chatterbot C:\Users\blah\Anaconda3\Lib\site-packages\chatterbot_corpus-1.2.0.dist-info C:\Users\blah\Anaconda3\Lib\site-packages\ChatterBot-1.0.2.dist-info

Looking at file "C:\Users\blah\Anaconda3\lib\site-packages\chatterbot\trainers.py", line 130 so function load_corpus exists.

---

def load_corpus(*data_file_paths):
    """
    Return the data contained within a specified corpus.
    """
    for file_path in data_file_paths:
        corpus = []
        corpus_data = read_corpus(file_path)

        conversations = corpus_data.get('conversations', [])
        corpus.extend(conversations)

        categories = corpus_data.get('categories', [])

        yield corpus, categories, file_path

Weird thing is I had a demo working using the chatterbot corpus months ago, straight from the demos/examples, odd I can't get it working on a fresh install.

Unfortunately this isn't something I've encountered before. It does seem strange that the function exists, but the ImportError is being triggered. Based on the version outputs you've posted, it looks like everything in your environment should be set up correctly.
