The imagecodecs-lite library fails to be built with Python 2 (Python 3 works fine). Therefore, one should add disabled = !isPy3k;.

@geistesk does this look ok to you? |

Building tifffile with Python 2.7 fails for me, because imagecodes-lite does not support Python 2.7. So can this not be removed?

The same applies to the patch above.

please leave it in for now. It's not unlikely that someone would choose to re-add Python 2 support.

I modified so imagecodecs-lite is only loaded for python3..let me know if this sounds good?

@jonringer when you want to have an environment that represents a build environment, that works well. Otherwise, I would recommend going of the nix run approach so setup hooks are not executed.
For example, having the following in a default.nix or shell.nix works when using nix-shell
with import <nixpkgs> {};
(python3.withPackages(ps: with ps; [ virtualenv tifffle matplotlib imagecodecs-lite ]).env
Note the env. When using nix run -f . that part should be removed
with import <nixpkgs> {};
(python3.withPackages(ps: with ps; [ virtualenv tifffle matplotlib imagecodecs-lite ])

in general that is my workflow. I guess I could do a default.nix like the on you have, then I could have just have a shell.nix be:
(import ./default.nix).env
I think that would work...

Also for my workflow, i need to be able to use virtualenv and then install some packages locally, the shellhook is nice in that case, because i can have it auto create the venv dir, set the pythonpath to include the venv sitepackages, and a few other project specific things :)
