Hi

When i was executing : python demo/pcd_demo.py demo/kitti_000008.bin configs/pointpillars/hv_pointpillars_secfpn_6x8_160e_kitti-3d-3class.py checkpoints/hv_pointpillars_secfpn_6x8_160e_kitti-3d-3class_20200620_230421-aa0f3adb.pth

I got a issue name "no module named": Traceback (most recent call last): File "demo/pcd_demo.py", line 3, in from mmdet3d.apis import inference_detector, init_detector, show_result_meshlab ModuleNotFoundError: No module named 'mmdet3d'

but already the folder exists. can any please help me in resolving this issue.

Hi, @Latha-13

Have you installed the mmdet3d in your environment? The existence of the folder 'mmdet3d' doesn't mean you have install mmdet3d successfully. Please refer to here.

Hi I have followed the steps given to install the mmdetection3d , Then how the module mmdet3d is not installed. can you please help me in solving the problem i have installed 2 times but the same error occurs . I have followed each and every steps in the installation process , That particular module alone is not installed is there any step for that.

• Have you successfully compiled the module (mmdet3d) and related module (mmcv, mmdet)? Or have you got the information that you have installed all modules successfully? If facing any error, would you mind posting your error report?
• If you installed the mmdet3d successfully, please type in python followed by import mmcv, import mmdet, import mmdet3d to check whether these modules can be imported.

I think it might be : can't find the path,maybe you can try to add : import sys sys.path.append('.') in pcd_demo.py

Hi

I tired to run the MMdetection3d in google collab i successfully installed mmdet3d but the issue is when i tried to run "mmdetection3d/demo/inference_demo.ipynb" i got the error ,

The code ran: from mmdet3d.apis import init_detector, inference_detector, show_result_pyplot

Choose to use a config and initialize the detector

config = 'configs/second/hv_second_secfpn_6x8_80e_kitti-3d-car.py'

Setup a checkpoint file to load

checkpoint = 'checkpoints/hv_second_secfpn_6x8_80e_kitti-3d-car_20200620_230238-393f000c.pth'

Error:

Like MMdetection do we have any google collab notebook for MMdetection3d for testing.
