Segfault using htop on AWS Sagemaker pytorch-1.10-cpu-py38 app

I am trying to launch the htop command in the Pytorch 1.10 - Python 3.8 CPU optimized AWS Sagemaker container. This works fine in other images I have used till now, but in this one, the command fails with a segfault:

htop 
htop: /opt/conda/lib/libncursesw.so.6: no version information available (required by htop) 
htop: /opt/conda/lib/libncursesw.so.6: no version information available (required by htop) 
htop: /opt/conda/lib/libncursesw.so.6: no version information available (required by htop) 
Segmentation fault (core dumped)

More info :

htop --version

Solution

  • I fixed this with

    # Note: add sudo if needed:
ln -fs /lib/x86_64-linux-gnu/libncursesw.so.6 /opt/conda/lib/libncursesw.so.6
