Google colab connection with Anvil regarding text to image generation

Anvil Q&A
1

What I’m trying to do:
I am trying to input some text in Anvil app and the google colab connected to Anvil sever will generate the image based on pre-trained model.

What I’ve tried and what’s not working:
I have got the following error. I don’t know what is wrong, so help me out?

anvil.server.SerializationError: Cannot serialize return value from function. Cannot serialize <class 'PIL.Image.Image'> object at msg['response']
at Form1, line 32
anvil.server.SerializationError: Cannot serialize return value from function. Cannot serialize <class 'PIL.Image.Image'> object at msg['response']
at Form1, line 32

Code Sample:

    # Get the results

  def click_button_click(self, **event_args):
    """This method is called when the button is clicked"""
  
    text_to_image = anvil.server.call('text_to_image', 
                                self.input_text.text)
    # If a category is returned set our species 
    if text_to_image:
      self.display.visible = True
      self.display.text = "The result is "
# this is a formatted code snippet.
# paste your code between ```

Colab Code

@anvil.server.callable
def text_to_image(input_text):
  model = clip.tokenize([input_text])
  return to_show_img

You can’t return a PIL Object from Server to Client without doing work to make it a Portable Class.

Here are the Python data types that can be passed between server and client:
