Error Installing mmdet (No module named 'numpy') #413

Closed AngSoonKim closed 3 years ago

AngSoonKim commented 3 years ago

Hi I wanted to try to use mmdet on android but when I pip install mmdet it gives and error of "No module named 'numpy'"

Is there a way to overcome this issue or it is not within what I am able to do on my end?

I pip install mmcv-full,numpy,cython,matplotlib,torch and mmdet. Only when mmdet is added, it fail to run.

The current version of mmdet (2.7.0) depends on mmpycocotools, which isn't currently available for Chaquopy. However, you may be able to work around this by using an older version. Try changing your install line to mmdet==2.3.0.

Thank you very much I am able to build it successfully using mmdet==2.3.0 I will try to see if I can still get the function I needed from mmdet. Thank you once again for your help.
