problem run with train.py #55

Warning: multi_tensor_applier fused unscale kernel is unavailable, possibly because apex was installed without --cuda_ext --cpp_ext. Using Python fallback. Original ImportError was: ModuleNotFoundError("No module named 'amp_C'") Epoch 0/119

    This probably means that you are not using fork to start your
    child processes and you have forgotten to use the proper idiom
    in the main module:

        if __name__ == '__main__':
            freeze_support()
            ...

    The "freeze_support()" line can be omitted if the program
    is not going to be frozen to produce an executable.

Hi @ahworld22 Please reinstall apex with --cuda_ext --cpp_ext. Or skip apex installation.

Hi @ahworld22 Please reinstall apex with --cuda_ext --cpp_ext. Or skip apex installation. Yea!But when i run as python setup.py install ,it done.When i run as python setup.py install --cuda_ext --cpp_ext,it always fails and says it cann't find the csrc/flatten_unflatten.cpp which is correctly in my files.

It always says: This probably means that you are not using fork to start your child processes and you have forgotten to use the proper idiom in the main module:

I think it's the problem with windows,it need the "main" to run multiprocess

ahworld22 commented 1 month ago

I use Windows to run the project ,but it seems something wrong.Because the train.py doesn't have 'main',which cann't do on Windows with multiprocess.
