Dependency on batman / numpy makes it impossible to install TLS about tls HOT 3 CLOSED

Yes this is a known problem with batman.
There are two work-arounds:

1. If you can accept an older numpy, then pip install numpy==1.21.1 (may need conda to force this exact version)
2. Download the batman package from Github, change numpy to oldest-supported-numpy in batman's pyproject.toml file and then doing a pip install .

If this doesn't get resolved soon (@lkreidberg please help, this is such a cool package), I will have to replace the usage of batman in TLS with e.g. PyTransit. Quite unfortunate situation.

Fixed by batman 2.4.9. Please try pip install batman-package --upgrade.
I will leave this issue open for a few week to check if it solves the problem for everybody.
In case any issues remain, I have prepared a TLS version that uses PyTransit instead of batman-package. I could then change it out.

Thanks so much for the quick reply, @hippke . That's done the trick!

I had already tried doing (1), but I would never have guessed I had to do (2) as well.

I have a lot of sympathy for the unfortunate situation you're in - it seems to me the Python community should be worrying much more about how hard it is to reproduce a known-good Python environment from three months ago!
