Process_data.py run error, display memoryError, I use win10, 8G memory, how to solve?

[ICfree]

python process_data.py ./GoogleNews-vectors-negative300.bin ./essays.csv ./mairesse.csv loading data... data loaded! number of status: 2467 vocab size: 30391 max sentence length: 149 loading word2vec vectors... Traceback (most recent call last): File "process_data.py", line 171, in w2v = load_bin_vec(w2v_file, vocab) File "process_data.py", line 104, in load_bin_vec word.append(ch) MemoryError

I feel that this problem is very likely because the binary data set read. /GoogleNews-vectors-negative300.bin is too large Ask how to solve it? ? ? How do everyone run?

Copy paste that code it optimizes and also resolves the encoding issue :)

Thank you for solving this code problem , however, the code indentation you sent does not seem to be uploaded. So could you please give the code with indentation, thanks.

[soujanyaporia]

Could anyone please submit a PR?

[amirmohammadkz]

@soujanyaporia I submitted a PR. I have made some other improvements in the training classes too. In my forked repository, you can see them. I can submit PR for them too.

[priyansh19]

I have done some changes and now process_data.py file is working Submitted a PR :+1: This is my Repository : https://github.com/priyansh19/personality-detection/blob/master/process_data.py
