spatiotemporal_det.py error #1524

Closed Ishihara-Masabumi closed 2 years ago

Ishihara-Masabumi commented 2 years ago

When I tried to use demo_spatiotemporal_det.py using the following command

python3 demo/demo_spatiotemporal_det.py --video demo/ex3.mp4

the following error message has occurred.

I think the error is clear as in the log: you need to install mmdet which is also stated in the installation file (https://github.com/open-mmlab/mmaction2/blob/master/docs/install.md):

d. Install mmdetection for spatial temporal detection tasks.

Thank you for your reply. BTW, my environment is CPU only. The solution of CPU only is the same as the above?

dreamerlin commented 2 years ago

I am afraid that CPU may not support some CUDA ops in MMDet

Ishihara-Masabumi commented 2 years ago

Then, how can I use mmaction2 on the environment of CPU only ?

hukkai commented 2 years ago

I would suggest that you run the code on the CPU first and then ask questions if there are errors. As I saw the codes for the action detection demo, it allowed the CPU device.

Ishihara-Masabumi commented 2 years ago

Thank you for your reply. Then, I will try to run the code next week!

Ishihara-Masabumi commented 2 years ago

Thank you. Today, I can run demo_spatiotemporal_det.py.
