Conda fails to install python-bioformats- incompatible with python 3?

[markemus]

I tried this in two environments, first with python3.9 and czifile installed, and then again in a fresh environment with python3.6. Same error.

conda install -c bioconda python-bioformats

returns

failed                                                                                 

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - python-bioformats -> python[version='<3']

Your python: python=3.9

Does the conda version not support python3 for some reason? I see it's been updated recently so I'd be surprised.

After further testing, I was able to conda install -c bioconda python-bioformats successfully in a Python 2 conda environment. That doesn't really work for us so hopefully someone is able to clarify- I know python-bioformats supports Python 3, so why does the conda version not support it? Is there another version I should be installing instead?

@markemus I just ran into this issue as well with same error-message. Did you find a solution or work-around?
Regarding Python 3 support I only found this pull-request. From the discussion there (particularly the last post), I am not sure that it supports Python 3. Is this stated somewhere? (in other words: what makes you so sure it supports Python 3, before I continue trying it...)

[markemus]

@michaelmell We have python-bioformats 4.0.0 installed with pip3 in Python 3.6.9 on another system- I didn't install it myself, but I don't think they had any trouble and it works fine.

Python3 is also listed as an option in the setup.py file: https://github.com/CellProfiler/python-bioformats/blob/master/setup.py

I don't know if it is still relevant but I had similar issue on windows 10.
The only way I managed to install it is to first install javabridge (not all python versions are supported, I'm working with 3.7):
https://anaconda.org/zacsimile/python-javabridge
and than install python-bioformats:
https://anaconda.org/bioconda/python-bioformats

I'm running python 3.9. Using https://github.com/CellProfiler/CellProfiler/blob/master/setup.py#L64, I installed as much as I could with conda/mamba but found that some required pip as the proper versions were not available at any of the conda repos:
python-bioformats==4.0.5
matplotlib<2.0.0
cellprofiler-core==4.2.1
pyzmq==18.0.1

A couple of notes:

• pip installing pyzmq gives an error with building the wheel, but subsequently succeeds with the legacy install.
• I think I also needed to pip install h5py==3.2.1 even though it's available in conda, or else I got the following error:
