Why use torch.multiprocessing.spawn for distributed training

9

Hi there, In the Swin UNETR scripts, e.g., https://github.com/Project-MONAI/research-contributions/blob/main/SwinUNETR/BRATS21/main.py, `torch.multiprocessing.spawn` is used for launching distributed training. Any reason why you didn't use `torch.distributed.launch`? Did `torch.multiprocessing.spawn` give better performance than `torch.distributed.launch`...

Hi! After I run: ``` cd impartial monailabel start_server -a api -s ~/ImPartial/Data/Vectra_WC_2CH_tiff/ ``` I get error: ``` [2022-11-22 09:48:21,068] [1509998] [MainThread] [INFO] (uvicorn.error:75) - Started server process [1509998] [2022-11-22...

Hi! I'm trying to run this notebook https://github.com/NVIDIA-Genomics-Research/rapids-single-cell-examples/blob/master/notebooks/5k_pbmc_coverage_gpu.ipynb within the container https://hub.docker.com/r/claraparabricks/single-cell-examples_rapids_cuda11.0 on A100 GPU. Everything works until executing this line ``` atacworks_results = coverage.atacworks_denoise(noisy_coverage, model, gpu, interval_size) ``` which...

Hi! The jupyter notebooks in the repo here https://github.com/NVIDIA-Genomics-Research/rapids-single-cell-examples/tree/master/notebooks are not exactly the same as the ones within the container https://hub.docker.com/r/claraparabricks/single-cell-examples_rapids_cuda11.0 (which has more comments). Which version is better? Thanks!
