AttributeError when training data

[laiyii]

Dear developer, I get an error when training data:

AttributeError: Can't get attribute 'RNA_SS_data' on <module '__mp_main__' from 'D:\\大四\\上学期\\机器学习及其在化学中的应用\\大作业\\workdir\\ufold_train.py'>

The file related to 'mp_main' is "C:\Users\fly\anaconda3\lib\multiprocessing\spawn.py", it seems like a multiprocessing error, could you please help me with this problem? Thank you!

I'm running with cpu)

Hi there,

You may refer to (

UFold/ufold/data_generator.py

Line 32 in 5f2be9c

p = Pool()

) and (

UFold/ufold/data_generator.py

Line 47 in 5f2be9c

self.seq = list(p.map(encoding2seq, self.data_x))

)
to change this to single core, but be aware that it will result in lower running time.

Thanks for your quick reply🌹
While I'm a beginner, still confused about how to change this to single core, could you please show me more details? Thank you.

I find the AttributeError results from windows system, the Pool.map function is failed (https://medium.com/@grvsinghal/speed-up-your-python-code-using-multiprocessing-on-windows-and-jupyter-or-ipython-2714b49d6fac)
it goes well when using linux.
