Are you running a script from an iCloud drive or the local files?
-
from cloud file
-
And when i Write a new code:
import matplotlib.pyplot as plt x=[1,2] y=[1,2] plt.scatter(x,y) plt.show()
i've got an error message for the first line
import matplotlib.pyplot as plt
"module 'matplotlib' has no attribute 'cbook'"
WHAT THE ...... !!??
-
Check if you don’t have 2 packages of matplotlib installed by coincidence.
-
There are known problems with running scripts from iCloud.
-
For me, this little script works also if in Pythonista iCloud
import matplotlib.pyplot as plt x=[1,2] y=[1,2] plt.scatter(x,y) plt.show()
-
And the big script also works....
