why does import pandas suddenly not work?
You can create a new environment on Anaconda and then install pandas in that environment. Otherwise, try re-installing Anaconda.
I am running the latest anaconda on ubuntu linux.  Everything was working ok until this week.  I can't import pandas on python3.  I could last week using the same programs.  I've tried it on python  called from the bash and also from spyder  and jupyter, and I get a message that it can't find pandas.  I've tried reinstalling pandas using both pip and conda, and it said that it was correctly installed.
Any suggestions?
Thank you.
