Is it possible to view numpy array as image while debugging in PyCharm?

I tried to enter

PIL.Image.fromarray(my_data, 'RGB').show()

into watches, but got

PIL is not defined

error. This is probably because PIL was not imported in current module.

Any other way appreciated. May be can write my own viewer or something?

I've just created OpenCV Image Viewer Plugin, which displays image while debugging just on click. You can install it to any JetBrains IDE, which support Python (directly or via plugin).

god bless u dude
It's seems cannot use to PIL.Image? Or there is the same tool to PIL.Image?
Unfortunately, it doesn't support PIL Images for now.

I was able to import packages with semicolon, and was able to show image with expression like below:

import matplotlib; matplotlib.pyplot.imshow(mydata)

AttributeError: module 'matplotlib' has no attribute 'pyplot'
Sometimes it is necessary to call matplotlib.pyplot.show(). Overall: import matplotlib; matplotlib.pyplot.imshow(mydata); matplotlib.pyplot.show()

As an alternative there is PixelLens for PyCharm which apart from Numpy also supports Pillow, Tensorflow and PyTorch image data:
