Description
Hello,
If I turn usetex=True, in rcParams and then try to save a figure using plt.savefig("xxx.eps") I get the error message at the end of the post.
I tracked this down, and the issue is with the temporary file created by tempfile.mkstemp() in the function _print_figure_tex on backend_ps.py. This file, when the username in windows is long, it is shortened to 6 characters + "~1", then when running latex, the ~ is interpreted as a line break, therefore giving the error.
I perform a simple fix on backend_ps.py, which is simply replace the short version of the username for the full name. This completely solves the problem for me:
fd, tmpfile = mkstemp()
#Fix#
tmplist=tmpfile.split("\\")
tmplist[2]=os.getenv('USERNAME').lower()
tmpfile="\\".join(tmplist)
#####Do not know how to proceed though in order for this "fix" to be checked/included/discarded...
Thanks!
Now the complete error message ( I changed the visible part of my username to xxxxxx):
import matplotlib.pyplot as plt
plt.rc("text", usetex=True)
plt.savefig("D:/test.eps")
