{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"obnoxious double warning at each script startup","articleBody":"For longer that I can remember, every time I start a script that imports matplotlib I get the following warnings:\r\n\r\n```\r\n/users/noel/.conda/envs/my_root/lib/python2.7/site-packages/matplotlib/backend_managers.py:62:\r\nUserWarning: Treat the new Tool classes introduced in v1.5 as experimental for now, the API will likely\r\nchange in version 2.1 and perhaps the rcParam as well\r\n 'version 2.1 and perhaps the rcParam as well')\r\n/users/noel/.conda/envs/my_root/lib/python2.7/site-packages/matplotlib/backend_tools.py:78:\r\nUserWarning: Treat the new Tool classes introduced in v1.5 as experimental for now, the API will likely\r\nchange in version 2.1, and some tools might change name\r\n 'version 2.1, and some tools might change name')\r\n```\r\n\r\nThese warnings are not only annoying, as I have no way to fix the code they refer to, but also lead to problems: by making the script output harder to parse, they often hide the actual output I want from the script. They are often longer than the useful script output.\r\n\r\nI have seen [suggestions](http://matplotlib.1069221.n5.nabble.com/Matplotlib-vers-1-5-0-warnings-td46543.html) to use the `warning` module to silence these messages, e.g.\r\n```\r\nimport warnings\r\nwarnings.filterwarnings(action='ignore')\r\n```\r\n\r\nbut I don't think this is a practical solution, as 1) I would need to add these two lines every time I create a new script that uses matplotlib (which is often), and 2) I would silence at the same time all the other warnings, that could be actually useful.\r\n\r\nmatplotlib 1.5.3 Python 2.7.12 on linux installed through conda, TkAgg backend.\r\n\r\nApparently not everyone sees those warnings.","author":{"url":"https://github.com/vnoel","@type":"Person","name":"vnoel"},"datePublished":"2016-11-04T18:05:20.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/7404/matplotlib/issues/7404"}
