Conda install and Error: No such command 'template-gui'.

[mauricev]

I’m trying to install with conda using environment.yml. At the very least, sklearn should be scikit-learn and traitlets is missing. However, I still get the error

Error: No such command 'template-gui'

upon running phy template-gui params.py

So I assume something is still missing.

pip needs to install the pre-release version of phy, but environment.yml as it currently exists will only grab the latest (non-pre) release. I just spent 15 minutes trying to figure out how to pass the pip --pre option in environment.yml but nothing I've tried seems to work. So for now, you can do the following.

1. Create your conda environment using the following environment.yml:

name: phy2
channels: 
  - conda-forge
dependencies:
  - python=3.7
  - pip
  - numpy
  - matplotlib
  - scipy
  - h5py
  - pyqt
  - dask
  - cython
  - pillow
  - scikit-learn
  - traitlets

> conda env create -f environment.yml

2. Install phy using pip from the command line:

> conda activate phy2
> pip install phy --pre --upgrade

This fixed the issue for me.

By the way -- we have had issues with the installation of certain QT Framework plugins when using either pip or the default conda channel. I recommend using conda-forge, and have edited the example environment.yml above to reflect that.
