run demo error #84

Closed MoonBunnyZZZ closed 5 months ago

MoonBunnyZZZ commented 9 months ago

During run common_demo.sh, there is ImportError:

ImportError: numpy.core.multiarray failed to import (auto-generated because you didn't call 'numpy.import_array()' after cimporting numpy; use 'numpy._import_array' to disable if you are certain you don't need it).

It seems like about grasp_nms package. How to fix it?

I put 'numpy.import_array()' after cimporting numpy in grasp_nms.pyx.The error don't occur.But I don't kown whether this is the only right way.

Maybe it's due to numpy version?

MoonBunnyZZZ commented 9 months ago

Maybe it's due to numpy version?

which version in your python env?In my env, it's 1.19.0.

chenxi-wang commented 9 months ago

I didn't remember the version. You can try upgrading numpy directly.

Could you provide more details about "gray point"?

Could it be the origin of the camera coordinates?

but, where is grasp_nms.pyx? I can't find it.

The function "nms" is aimed at non-maximum suppression. I commented out the line 108 [e.g. gg.nms()] of the demo.py file directly, which seems to have no great effect on the results of the example.

I'm also getting this error, but I can't find where the “grasp_nms.sh” file is, how did you fix it, could you tell me please?
