As far as conda environments go, I don't want to be the clueless newbie who
disses something I barely understand. Suffice it to say that I haven't
been able to create conda environments for Python 3.6 or 3.8 that work with
Qt. It's likely a setting somewhere, perhaps a setting that should have
been deleted, and wasn't...
For now, I'm happy to use just Python 3.7. That being so, I did the
following:
1. Create py37, based on my base env: `conda create --name py37 --clone
base`
2. Create holo37, based on py37: `conda create --name holo37 --clone py37`
Both of these envs run Leo properly.
3. Within the holo37 env, I used pip to install packages, in the order that
Thomas used (without installing Leo):
- matplotlib
- bokeh
- holoviews
Note: matplotlib and bokeh had already been installed. My guess is that
these two packages are part of the full Anaconda distro, but maybe I had
installed them somehow previously.
Finally, I pip installed holoviews. Success. This *uninstalled* and then
*reinstalled
*bokeh, and also holoviews.
*Still to do*
The following still crashes:
import holoviews as hv
hv.extension('matplotlib')
Presumably I need to install something else.
*Summary*
Using pip to install matplotlib, bokeh and holoviews works on a Python 3.7
conda environment.
Still to do: allow holoviews to use matplotlib.
I still don't understand how to use conda to create Python 3.6 or 3.8
environments, but I don't care much at present :-)
