urm a weird Conv.cpp seems to have snuck into this push - let me fix that. |

What was the rationale behind this? I can't set random seeds in my CPU multiprocessing code because it's trying to set CUDA seeds. This might be more convenient than controlling CUDA seeds manually, but this seems like a bug to me. File "/home/ka709/ferry/test.py", line 13, in test
torch.manual_seed(args.seed + rank)
File "/home/ka709/miniconda3/lib/python3.6/site-packages/torch/__init__.py", line 133, in manual_seed
torch.cuda.manual_seed_all(seed)
File "/home/ka709/miniconda3/lib/python3.6/site-packages/torch/cuda/random.py", line 37, in manual_seed_all
_lazy_init()
File "/home/ka709/miniconda3/lib/python3.6/site-packages/torch/cuda/__init__.py", line 83, in _lazy_init
"Cannot re-initialize CUDA in forked subprocess. " + msg)
RuntimeError: Cannot re-initialize CUDA in forked subprocess. To use CUDA with multiprocessing, you must use the 'spawn' start method |
