Hello I am new using Nvidia.
I already had CUDA 12.6 but I download and Install CUDA toolkit 12.9. As I noticed that the environment I need to work is 12.6 I decided to remove CUDA toolkit and install once more the CUDA toolkit 12.6.
For the removal I used the following link’s instruction.
After downloading and installing the CUDA toolkit 12.6 once more, i check the CUDA version using the command nvidia-smi but it still appear as N/A.

I try to run the CUDA install command once more but it shows as it is already installed.
nextorage_ai@nextorageai-desktop:~$ sudo apt-get -y install cuda-toolkit-12-6 cuda-compat-12-6

cuda-compat-12-6 is already the newest version (12.6.36890662-1).
cuda-toolkit-12-6 is already the newest version (12.6.11-1).

I am a confused as what should I do next. Did I made a mistake removing the CUDA toolkit? How can the version show in the nvidia-smi command?
Thank you very much in advance
