Install OpenPCDet on GOOGLE Colab platform, but RunERROR: Error compiling objects for extension

[Cappuccinoll]

Hi,

i want to try demo.py on Google Colab platform. All is perfect but when i want to install 'pcdet' library python setup.py develop i meet an error, this

my version (default version of colab): pytorch 1.11.0 cuda 11.3 cmake 3.22.5 python 3.7.13

does someone have the same problem and how to solve that? i try a lot of version combinations but have no effect.

Thanks!

Have you successfully installed ? I also want to run in Google Colab but it shows that google colab don't support the visualization tools so it can't show the image with 3d object detection bouding box. With the setup.py I can run on Google Colab but now I want to run it locally on VSCode but also got the same error as you are. I think it is about Pytorch and CUDA compatible version problem. What version are you using?

@Cappuccinoll @leducnguyen21 Hello, I've occurred this before and I solved it. You can refer to README of https://github.com/OrangeSodahub/CRLFnet#install--build In the part of INSTALL & BUILD

There pointed out the version of Pytorch and cuda. And any other problems when using OpenPCDet could also refer to it.
