Hi,

I am running Julia version 0.5.2 with Atom. Everything was working fine then at some point I start to receive the error message below every time I try “using PyPlot”.

Please let me know if anyone has any ideas of how to overcome this issue.

thank you

I solved this problem by doing:

conda install -c anaconda sip=4.18

thanks !
