target_params.pkl open using pyhotn3 pickle failed.

[lucasjinreal]

hi, I am trying run this repo under pyhton3, original implements using python2, code is fine but the target_params.pkl can not open, do you have an alternate version of that file which can open using python3?

I think you can use pickle in python 3 instead of cPickle:

try:
    import cPickle as pickle
except:
    import pickle

I tried the same but it's not working.

Improved the code to
target_params = pickle.load(open('save/target_params.pkl','rb')) .

Gives the following error:
ImportError: No module named 'numpy.core.multiarray\r'

Tried to resolve the \r issue using this answer.

Yet the issue remains. Get this message.
TypeError: a bytes-like object is required, not 'str'

Can we create a new pickle for python 3 to resolve them?

[lucasjinreal]

I think original author save the data using python2.7 cPickle which may not can be properly opened by Python3 pickle, would original author resave this file using python3 for compatiable?

[LantaoYu]

This should work:

import pickle
target_params = pickle.load(open('save/target_params.pkl', 'rb'), encoding='latin1')

Still not working.

I have added a new pickle file in python 3: https://github.com/LantaoYu/SeqGAN/blob/master/save/target_params_py3.pkl

Now you can read it with

import pickle
target_params = pickle.load(open('target_params_py3.pkl', 'rb'))
