It looks like the pixel manipulation functions of nansat were not compiled during the installation. There was an issue with the package metadata that might have caused this. It has been fixed in nansat 1.6.2. The issue with the pixel functions might also come from your environment. You need to have a C compiler and GDAL installed.
Here are some steps you can take to try and fix this:
pip install nansat==1.6.2
