and when i fixed this problem i get

I'm afraid I cannot help you - I have no idea what code you are trying to run.

One idea is to run python example.py from within the scripts/ directory in this repo. That runs a very basic test of model fitting.

[FoolishBrown]

thank you for you answer.when I run python example.py ,I also have a problem :PicklingError: Can't pickle <function func_wrap at 0x000000000AAF63C8>: it's not found as lopq.utils.func_wrap.what's the reason for this issue.

[pumpikano]

This is very strange because there is no pickling involved anywhere in example.py. I am not familiar with Python on windows, but perhaps you should try test whether your Anaconda installation is correct?

[FoolishBrown]

Thank you for you answer.I can confirm the anaconda installation is no problem.I found the function named 'func_warp' is a nested function in the function 'parmap' in utils.py.Whether the reason is the different handling mechanism between the Win and Linux? I guess...

I just met up with the same problem, did u figure it out?

[anas-899]

@Hugh0120 did you solved the issue? I am facing the same problem?
thanks

@Hugh0120 did you solved the issue? I am facing the same problem?
thanks

well, actually I didn't fix the issue and finally used another library called FAISS, hope that could help.
