TqdmKeyError: "Unknown argument(s): {'colour': 'blue'}"

When installing the latest version and running the first ODE system example on your README page, I get this error. More details:

OK, this seems to be only an old python version issue.

Could be a tqdm version issue. Can you share the version of tqdm that causes the problem? Try pip list | grep -i tqdm.

The version of tqdm was 4.42.1 (with an environment based on python 3.7.6). A new environment (python 3.9) installed tqdm version 4.64.0 and solved the problem. Thanks!
