Cloud Pickle/Serialization Errors

[Jonah1234567]

When working with images (especially large PNG's that are heavily compressed), the images can have issues going over the wire both in PIL form and in NumPy array form. The error mainly seems to occur when sending multiple images, although it may be a product of PNG decompression and cloud pickle trying to pickle libraries with images. This was run on Colab with Node 16.15.0 and Python 3.7.13.

Error:
No error recorded but the console will stop at the uploading stage of deployment.

Images tested with:
While the Mario image is quite large, the job succeeds when it is sent alone, suggesting there could be issues regarding pickling multiple images at once.
