Incompatibility with python3

[ghost]

Hi there,
I tried to install astroML via pip, but it failed due to the new print syntax of python3 with respect to python2.

Yes, astroML is currently not compatible with Python 3. We've talked about how to make it compatible, but it will be a significant amount of work to make sure that all ~200 figures are still correctly created under the new Python version. If anyone has ideas on how to approach that, I'm all ears.

Note: the Python 2 dependency is explicitly listed in both the README file and in the setup.py file

Also, I should add that it's a lot deeper than simply changing print foo to print(foo). There are some subtle changes between 2.x and 3.x which will also come into play.

Yep, sorry I didn't check the readme file before writing.
Sorry again and thanks for the great work

[jakevdp]

Actually, I'm kind of surprised that pip even tried the installation, when the setup metadata explicitly says it's only compatible with Python 2. Oh well...

That is probably just a bug in the macports version of pip3, it's not the first time it failed with python2 only packages

I just pushed changes to master adding Python 3 compatibility. I plan to do a new release soon so that it can be installed from pip. Thanks!

Great news! Thanks to you for the hard work

I also wait for the new version on Pypi, so I can replay

ok, I did create a temporary package from github

[jakevdp]

I'll try to do the release this week

Hey
Any news on an estimate when astroML will be compatible to Python 3.x?

thanks

edit: nevermind. This has apparently been fixed already, just installed successfully 😊

[jakevdp]

Sorry – I've been slow on the new release. I'll try to make it happen soon!

This is now fixed in the 0.3 release. Thanks!
