If I use my 32bit version of python the plot works fine, but I get a memory error when I use pickle, so I switched to 64bit python. But now I get this error when I try to save the plot.
Read documentation of savefig (https://matplotlib.org/api/_as_gen/matplotlib.pyplot.savefig.html).
dpi parameter is specified as float, whereas you passed a string.
Try with dpi=300 (without apostrophes).
