Automatic pipeline assembly crashing on colab

@MuroriM Do you want to self-assign this or you need someone else's help?

I'm working on other issues at the moment. If someone else is available to look at it at the moment, that would be helpful.

@MuroriM Can you post a way to replicate the error?

And after that, @zhangir-azerbayev can you take a look and figure out what happens?

To replicate the error:

• Go to the colab notebook
• Run the two cells under ### Using automatic pipeline assembly
  (the single doc and multi-doc pipeline assembly cells)

They both take a long time and end up using more RAM than allocated on Colab causing the notebook to crash. Using the colab hosted GPU or TPU does not help.
