Preparing the Environment of MMDetection 3D on windows11

Question

While preparing an environment with PyTorch and after installing all the packages needed using the miniconda terminal, an error showed up in the final step of the process which is the verifying of installation.

I created a conda environment and activated it, then I installed PyTorch and all the packages needed using MIM.

• MMEngine
• MMCV
• MMDetection
• MMDetection3D

I also successfully downloaded config and checkpoint files using the following command ;
mim download mmdet3d --config pointpillars_hv_secfpn_8xb6-160e_kitti-3d-car --dest

However in the final step to verify the installation I got the error message.

from mmdet3d.apis import init_model, inference_detector


config_file = 'pointpillars_hv_secfpn_8xb6-160e_kitti-3d-car.py'
checkpoint_file = 'hv_pointpillars_secfpn_6x8_160e_kitti-3d-car_20220331_134606-d42d15ed.pth'
model = init_model(config_file, checkpoint_file)
inference_detector(model, 'demo/data/kitti/000008.bin')

Output

The Error message is shown below and in the screenshot from jupyter notebook.
