title: No module named 'pandas' despite it's clearly installed?
body: <p>Sorry I know this has been asked several times on the forum but I'm not quite able to debug this problem. Basically I would like to run my snakefile (using snakemake), but it's not recognising pandas from the line 'import pandas as pd'. I'm able to see it when I type 'pip show pandas', or 'pip3 show pandas'. It's also up to date according to 'conda update pandas' which says 'All requested packages already installed'. Just wondering if anyone has any idea other than reinstalling the whole python/anaconda?</p>
  <p>Thanks!</p>
