[Qgis-user] Pandas in QGIS - MAC

[William Kyngesburye]

The QGIS 3 readme has instructions about installing extra python modules.  Note that you use "pip3", not pip, to make sure you get the python 3 version.  Also, not mentioned in the readme - since you have Anaconda installed, even pip3 may install for Anaconda, so you may need to give the full path to pip3:

sudo /Library/Frameworks/Python.framework/Versions/3.6/bin/pip3 install pandas

Theory of the Universe

There is a theory which states that if ever anyone discovers exactly what the universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarrely inexplicable.  There is another theory which states that this has already happened.
