Hi @sciarrilli, curses is a builtin module for Python on Unix. The log looks like you are using a conda environment. Your Python interpreter might miss some requirements. Could you try:

/usr/bin/pip3 install --user uv
~/.local/bin/uvx nvitop

Thank you @XuehaiPan I resolved the issue. In the conda env I cannot do pip3 install --user. But I was able to use nvitop outside of the conda env I was working in.
