Pweave resulting in MultipleInstanceError after updating anaconda

Question

After updating to the current version of Anacondo (Anaconda3-5.0.0-Windows-x86_64), my pweave code has run into some issues.

When running for example

pweave.weave('example.texw', doctype = 'tex')

I get the MultipleInstanceError with the traceback shown below:

Traceback (most recent call last):

MultipleInstanceError: Multiple incompatible subclass instances
InProcessInteractiveShell are being created.

I can however run pweave from the terminal as

pweave -f tex example.texw

I have not found relevant answers regarding the MultipleInstanceError elsewhere. Any insight would be greatly appreciated!
