Error "Invalid argument" running on windows, python 3.5

[tuan-seoultech]

I try to run the implementation with python 3.5 on windows 10.
I have to change some function to change from python 2.x to python 3.5 such as:
print "hello" ---> print("hello")
xrange() --> range()
izip --> zip
Change some import style
Finally, I can run data preparation.
Then when I try to train network from lsp dataset and pretrained AlexNet.
+It load the input data successfully.
+Then, the error come when it run the code in function evaluate_pcp in regressionnet.py.
for i, batch in tqdm(enumerate(test_it), total=num_batches):
I think it comes from the reading data with multithread, but I don't know where the bug come from, and how can I debug the error.
Please guide me how can I check the error, thank you.

The following is the stack trace:

Sorry, the code is written in python 2.7. I'm not planning to support 3.5.
It might happen that some more thing should be changed to be compatible with python 3.5.
