Trouble using Nsight Compute on Google Colab: 'command not found' error with ncu and installation script error with Nsight Compute

Question

I am trying to use ncu on Colab, however when I type

ncu
/bin/bash: ncu: command not found

A few days ago this command was working fine, I am unsure if I am making some mistakes in the code or if it is a problem with colab.

And I cannot install Nsight because if I run this:

!chmod +x  /content/drive/MyDrive/ncu/nsight-compute-Linux-2023.1.0.16-32451174.run
!/content/drive/MyDrive/ncu/nsight-compute-Linux-2023.1.0.16-32451174.run  --confirm

It shows after the license it presents this error

The program './install-Linux.pl' returned an error code (1)

I cannot use nvprof because of this error (nvprof is no longer supported on new architecture)

Here are instructions to install CUDA Toolkit 12.1 on Google Colab, which includes Nsight Compute:

1. Download and install CUDA 12.1 from NVIDIA's installer

! set -x \
&& cd $(mktemp -d) \
&& wget https://developer.download.nvidia.com/compute/cuda/12.1.0/local_installers/cuda_12.1.0_530.30.02_linux.run \
&& sudo sh cuda_12.1.0_530.30.02_linux.run --silent --toolkit \
&& rm cuda_12.1.0_530.30.02_linux.run

2. Add CUDA binaries folder to PATH

import os
os.environ['PATH'] = os.environ['PATH'] + ':/usr/local/cuda/bin/'

3. Run Nsight Compute!

! ncu --version
