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):

AttributeError: module 'inspect' has no attribute 'signature'

Any ideas on how to fix this issue?

  • does installing the complete module help? `pip install -U dask[complete]` – ificiana Jul 07 '22 at 18:32
  • Same issue. I uninstalled dask, purged the pip cache, and installed with pip install -U dask[complete]. – Isaacnfairplay Jul 07 '22 at 20:47
  • flask imported without issue on my personal machine. The python version is 3.10.5 where the failure was on 3.10.4, but it is unlikely this issue is python version related. I will try in a clean venv on the older python version and update this thread. – Isaacnfairplay Jul 08 '22 at 02:35

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)
