A pure hack, but updating site-packages/messytables/core.py to change "from collections import Mapping" to "from collections.abc import mapping" worked for me.

I would like to point out a small error here, it should be from collections.abc import Mapping. For anyone looking for a detailed explanation of this issue, see this question.

I had the same issue, my solution was to manually edit the file in my Dockerfile after I imported it yolo. Can't we get a new release?

Just in case this helps someone, the code below does the suggested edits on google colab.

filename = "/usr/local/lib/python3.10/dist-packages/messytables/core.py"

print("Before:")
!cat {filename} | grep import

!sed -e 's/from collections import Mapping/from collections.abc import Mapping/g' {filename} > tmp.txt
print()
print("Check:")
!cat tmp.txt | grep import

!mv tmp.txt {filename}

print()
print("After:")
!cat {filename} | grep import
