name 'Path' is not defined

I can run my scripts successfully, however, when I want to run kernprof -lv my_scirpt.py --parameters, this error message happened:

I could not figure not which part matters cause I already put from pathlib import Path in the head of my scripts. Could you give me some suggestions to fix this?

I don't immediately see the issue. Please provide a MWE and maybe I can help more.

Actually I am profiling the open project nerfstudio, tag v0.2.2.

Sample data can be download from here.

Since it will generate a config.yml during the training process, the path inside the config.yml would not be consistent if I share this to you.

Thus, I suggest you to follow the path:
I. install nerfstudio
II. at the nerfstudio working directory, python scripts/train.py nerfacto --data data/fox --max-num-iterations 3001, reducing the max-num-iterations could save time.
III. kernprof -lv python scripts/render.py --load-config xxxxx/config.yml --output-path ./renders --output-format images

then comes the error above.
Thank you for your help.
