I am running some NLP models and simply using wandb to log the errors during these modelings. I am receiving the following error while logging:

`wandb: ERROR Failed to sample metric: psutil.NoSuchProcess process no longer exists (pid=453)`

I appreciate your help in fixing it.

Hi @faizelkhan-umn, happy to help you look into this but we will need additional info. Could you please provide the following:

- Brief description of your experiment setup and what integrations, if any, are you using? Expand on the structure of your runs including if you are running anything in parallel or if you are using multiple GPUs.
- Complete traceback of your error
- `Debug.log` and `Debug-internal.log` files for the crashing runs. These are found in the working directory of the project under `wandb` within the specific runs folder.

I don’t know if @faizelkhan-umn fixed his issue or not, but I’m also facing the same issue.

I’m not using any special integrations, or multiple GPUs.

Here’s the trace of my error:
