Re: [Matplotlib-users] Can not display 3D plot !

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

I tried that:

from mpl_toolkits.mplot3d import axes3d
import matplotlib
import matplotlib.pyplot as plt
import faulthandler
import os

print os.getcwd()
#with open("./error-log.txt", "wb") as f:
#    faulthandler.enable(f)
faulthandler.enable()

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
X, Y, Z = axes3d.get_test_data(0.05)
cset = ax.contour(X, Y, Z)
ax.clabel(cset, fontsize=9, inline=1)

plt.show()

And I don't get any error, even if it still crashes :)

Do you have an idea to make the faulthandler able to catch the errors?
Did you received the Windows error log/traceback I sent you? I think it is
the most detailed traceback we have for now.
