Unable to build packages for OpenPCDet operations

[DevankGarg]

Hello,

First of all, thank you for providing such a good-quality dataset. I was trying to evaluate one of the pre-trained models, so I followed the steps in the detection readme, so on step 7 I am unable to build the OpenPCDet package.

Can you please help

Traceback (most recent call last): File "D:\4D RADAR\K-RADAR\K-Radar\radar\lib\site-packages\torch\utils\cpp_extension.py", line 1740, in _run_ninja_build subprocess.run( File "C:\Users\Admin\AppData\Local\Programs\Python\Python38\lib\subprocess.py", line 516, in run raise CalledProcessError(retcode, process.args, subprocess.CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.

It looks like the issue related to incorrect path set for CUDA_HOME. Could you please check by running the following commands?

$ nvcc -V
$ echo $CUDA_HOME

If the CUDA version displayed from these commands does not match, try the following steps to set the desired CUDA version. For instance, if you want to use CUDA version 11.3, you can do the following:

$ cd /usr/local
$ sudo rm cuda
$ sudo ln -s cuda-11.3 cuda

$ gedit ~/.bashrc

Add the following lines to your ~/.bashrc file:

export PATH=$PATH:/usr/local/cuda-11.3/bin
export CUDADIR=/usr/local/cuda-11.3
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-11.3/lib

After saving the changes, reactivate your ~/.bashrc file by running:

$ source ~/.bashrc
