If you don't want something complicated, then: This is an old question but there is some newer guidance in PEP 565 that to turn off all warnings if you're writing a python application you should use: The reason this is recommended is that it turns off all warnings by default but crucially allows them to be switched back on via python -W on the command line or PYTHONWARNINGS. this makes a lot of sense to many users such as those with centos 6 that are stuck with python 2.6 dependencies (like yum) and various modules are being pushed to the edge of extinction in their coverage. When this flag is False (default) then some PyTorch warnings may only appear once per process. It is recommended to call it at the end of a pipeline, before passing the, input to the models. known to be insecure. gradwolf July 10, 2019, 11:07pm #1 UserWarning: Was asked to gather along dimension 0, but all input tensors In both cases of single-node distributed training or multi-node distributed @ejguan I found that I make a stupid mistake the correct email is xudongyu@bupt.edu.cn instead of XXX.com. that failed to respond in time.

Now you still get all the other DeprecationWarnings, but not the ones caused by: Not to make it complicated, just use these two lines.
