I’m using PyTorch under Win10, and when apply DataParallel to models, the following warning appears:
- C:\Anaconda3\lib\site-packages\torch\cuda\nccl.py:27: UserWarning: PyTorch is not compiled with NCCL support
warnings.warn(‘PyTorch is not compiled with NCCL support’)
- Is it because my pytorch was installed under Win10?
- Does it slow down the program?
