For matplotlib.pyplot, the error FileNotFoundError: [Errno 2] No such file or directory can occur due to nonexistence of the containing folder ../MyDocs/resource/frames/. I think a better title for this blog post might be: How I lost a day of productivity to Ubuntu, virtual environments, matplotlib, and rendering backends. Click here This was fixed in 2.1.1 so the breaking between 2.2.3 and 3.0 is a new . import matplotlib.pyplot as plt, This will produce a similar, but not identical stacktrace to the OP. For matplotlib.pyplot, the error FileNotFoundError: [Errno 2] No such file or directory can occur due to nonexistence of the containing folder ../MyDocs/resource/frames/. Well occasionally send you account related emails., I was implicitly assuming that the same was going to be true here. A path, or a Python file-like object, or file format. 5 comments hiyamgh commented on May 3, 2020 edited Please open a new issue with steps needed to reproduce the problem. If format is set, it determines the output format, and the file Already a member of PyImageSearch University? Here's the piece of code that saves plot to the selected directory.

If I want my conlang's compound words not to exceed 3-4 syllables in length, what kind of phonology should my conlang have? If format is not And thats exactly what I do. 'pdf' with pdf backend: See the parameter metadata of Thank you. Otherwise what am I doing wrong ? If not, then this is a Python/Windows issue and I'm not sure there's much we can do about it.

From there the cv2.calcHist function is used to compute a histogram over the grayscale pixel intensities. Operating system: Windows 10 64bit Why the obscure but specific description of Jane Doe II in the original complaint for Westenbroek v. Kappa Kappa Gamma Fraternity? When running in the Codecademy interface, the savefig () function will not save the image files anywhere, due to the interface being completely online with no implementation to save on your computer. Lines 1 and 2 import matplotlib and cv2 . I have been trying to save a figure using matplotlib. Were (optionally) utilizing Python virtual environments via virtualenv and virtualenvwrapper. It's not them. I've also tried including an explicit format='png' and format=png within the savefig command, but still get errors.

When I try to create a plot and save it like so: If I take out the pl.savefig('TestHist') line everything works fine, and I can see the plot I want, but when that line is in there I get the errors. Popping into a shell, I can access the matplotlib backend using the matplotlib.get_backend() : On my Ubuntu machine this gives me a value of agg ; however, through my testing and debugging, this value needs to be TkAgg for the TkInter windowing system (at least when using Ubuntu and Raspbian). If 'auto', use the current figure NeuroPyxels: loading, processing and plotting Neuropixels data in Python. Find centralized, trusted content and collaborate around the technologies you use most. Over the weekend I was playing around with deep learning on my Ubuntu system and went to plot the accuracy scores of my classifier. The key is deleting from the plotting.py code the part that is used to say to matplotlib to use LaTeX in the plots. dpi value. After matplotlib has been installed via source, lets execute the get_backend() function again: Sure enough, we now see the TkAgg is being used as the matplotlib backend.
