progress_apply bug: TypeError: unhashable type #862
Description
- I have marked all applicable categories:
- exception-raising bug
- visual output bug
- documentation request (i.e. "X is missing from the documentation." If instead I want to ask "how to use X?" I understand StackOverflow#tqdm is more appropriate)
- new feature request
- I have visited the source website, and in particular
read the known issues - I have searched through the issue tracker for duplicates
- I have mentioned version numbers, operating system and
environment, where applicable:import tqdm, sys print(tqdm.__version__, sys.version, sys.platform)
tqdm: 4.40.1
pandas: 0.25.3
python: 3.7
