title: pycharm error happening at random time: Process finished with exit code 134 (interrupted by signal 6: SIGABRT)
body: <p>I am working with pycharm community on a tensorflow model with keras backend, sometimes this error appears in a random time, specially after I call pyplot and close the window:</p>
  <pre><code>Exception ignored in: &lt;bound method Image.__del__ of &lt;tkinter.PhotoImage object at 0x7ff6406fad30&gt;&gt;
  Traceback (most recent call last):
    File &quot;/usr/lib/python3.6/tkinter/__init__.py&quot;, line 3507, in __del__
      self.tk.call('image', 'delete', self.name)
      RuntimeError: main thread is not in main loop
  </code></pre>
  <p>After this error, I need to close the python console and load my data again which is time-consuming (the data is a big dataset and the memory usage is considerable)</p>
  <p>How do I resolve this problem?</p>
  <p>UPDATE:
  Here is the plot code:</p>
  <pre><code>import matplotlib
  matplotlib.use('TkAgg')
  from matplotlib import pyplot as plt
  import numpy as np
  
  data = np.ones((256,256))
  fig = plt.figure()
  ax = fig.add_subplot(111)
  temp = np.transpose(data)
  plt.title('title')
  im = ax.imshow((temp), aspect='auto')
  fig.colorbar(im)
  plt.axes()
  
  data2 = np.ones((256,256))
  fig = plt.figure()
  ax = fig.add_subplot(111)
  temp = np.transpose(data2)
  plt.title('title')
  im = ax.imshow((temp), aspect='auto')
  fig.colorbar(im)
  plt.axes()
  </code></pre>
  <p>UPDATE 2:</p>
  <p>I have PyCharm 2021.2.3(Community Edition)</p>
  <pre><code>build PC-212.5457.59
  Runtime version: 11.0.12+7-b1504.40 amd64
