import toolz results in an AttributeError during dask import

Question

The python command

import dask

Results in a long error chain to one of its dependencies.

I can replicate deeper parts of this error chain by importing tlz.

import tlz

Traceback (most recent call last):

Any ideas on how to fix this issue?

Answer 1

Fixed issue by removing an extra set of python installations on my computer.

Details here: Create venv without admin access python

The following command works as expected

import dask
help(dask)
