I am using pycharm with a remote interpreter.
When I try to use matplotlib I get the following error:
>>> import matplotlib.pyplot as plt
Backend TkAgg is interactive backend. Turning interactive mode on.
Failed to enable GUI event loop integration for 'tk'

How can I solve?

Connect to a remote server and open the remote project Ensure you have the Remote Development Gateway plugin enabled. On the PyCharm welcome screen, select Remote Development. In the Run the IDE Remotely section, click SSH Connection.
You can launch an SSH Session right from PyCharm. By running commands in a dedicated SSH terminal, you can access data on a remote Web server or the default remote interpreter via an SSH tunnel, mainly upload and download files.
Change the Python interpreter in the project settingsPress Ctrl+Alt+S to open the IDE settings and select Project <project name> | Python Interpreter. Expand the list of the available interpreters and click the Show All link. Select the target interpreter.
This feature requires xlwings PRO and at least v0. 27.0. Instead of installing Python on each end-user's machine, you can work with a remote Python interpreter. This works the same as a web application, but uses your spreadsheet as the frontend instead of a web page in a browser.
First, you need to forward X11 connections to your local machine (ssh -X ... for linux, for windows you can use VcXsrv and setup the forwarding in your ssh client).
Next, set the DISPLAY environment variable in your run configuration as described here: https://stackoverflow.com/a/32945380/2708478
After that, plt.show() will show the plot on your local machine.

I had the same problem and fixed it by changing to a non-interactive backend:
import matplotlib
matplotlib.use('Agg')
