Description
Hi guys, I'm recently trying to use torch.profile for profiling of a large NLP model. However, I have encountered some problems and would like to get some advice:
-
I found that only
with_modules=Trueandwith_stack=Trueare set at the same time, the tensorboard page will display the view of module. Otherwise, the module view option cannot be found in the browser, like:

-
In the view of module, there is no device time data, but I have added
ProfilerActivity.CUDAin profile activities.

Here is an example of my code :
with torch.profiler.profile(
activities=[
torch.profiler.ProfilerActivity.CPU,
torch.profiler.ProfilerActivity.CUDA],
schedule=torch.profiler.schedule(
skip_first=5,
warmup=1,
wait=10,
active=5),
on_trace_ready=torch.profiler.tensorboard_trace_handler('./tensorboard'),
with_modules = True,
with_stack = True
) as prof:
for i in range(steps):
do training
prof.step()
I'm not sure if this is a version related issue, here is my version info:
torch 1.13.1+cu117
torch-tb-profiler 0.4.1
torchaudio 0.13.1+cu117
torchvision 0.14.1+cu117
UPDATE: Today I upgraded torch version, but this problem still exists:
torch 2.0.0.dev20230226+cu117
torch-tb-profiler 0.4.1
torchaudio 2.0.0.dev20230223+cu117
torchvision 0.15.0.dev20230226+cu117

Research direction
No repository file or test is named. Reproduce the provided torch.profiler example with the listed torch-tb-profiler versions, enabling CUDA activity, with_modules, and with_stack, then inspect the generated TensorBoard trace and module view. Done means the module view is available as expected and includes device-time data, or the limitation is documented.
