The “conda install -c pyviz holoviz” step fails with
“ERROR conda.core.link:_execute(700): An error occurred while installing package ‘defaults::rise-5.6.1-py37_1’”
I hit this on EC2 instances running AWS’ latest Ubuntu image: With both Anaconda and Miniconda. The Miniconda try was from a clean slate machine.
The install for Miniconda is currently Python 3.8 so after a few permutations of Miniconda installs and the environment creation command (python=3.7 or python=3.8) I found the suggestion to do conda install python=3.7 after installing 3.8… hope springs eternal; but this merely changed the error number from 698 to 700. I will include top and bottom portions of the diagnostics below.
