AssertionError: fused_bias_leakyrelu miss in module _ext

[lpkoh]

I am running Ubuntu 18.04. I have installed mmcv==1.3.3, mmdet==2.7.0, using openmim.

I face the following issue when importing from mmdet.core

Traceback (most recent call last):

Could someone advise?

Please run python mmdet/utils/collect_env.py, and paste all information here.

Hi, I have run it and this is my result:

I tried running with "python" instead of "python3" instead, same result.

If it helps, I am currently using a Jetson AGX Xavier flashed with Jetpack 4.6. I am using python 3.6.9 in venv. I have installed:

• mmcv 1.3.3
• torch 1.10.0
• torchvision 0.11.1
• openmim 0.1.5
• mmdet 2.7.0

I installed in the above order first. After that, I ran the following commands:

pip install -r requirements/build.txt
pip install -v -e .

as per https://github.com/deepinsight/insightface/tree/master/detection/scrfd

It seems that mmcv-full was installed improperly .which command did you use to install mmcv?

[lpkoh]

I might have used mmcv==1.3.3 instead of mmcv-full==1.3.3.

I am retrying installation with mmcv-full right now. Could this be the reason?

Hi, I have reinstalled my mmcv-full.

I ran python3 mmdet/utils/collect_env.py, and this is what I got:

I ran the command python3 tools/scrfd2onnx.py config configs/scrfd/scrfd_2.5g.py checkpoint pytorch\ weights/scfrd_2-5g.pth --input-img 0.jpg --shape 640 from https://github.com/deepinsight/insightface/tree/master/detection/scrfd and had the following issue when importing from mmdet.core:
