Issue installing holoviz tutorial

alberto-dellera · January 3, 2023, 4:57pm

Warning: I am a newbie in both Miniconda/Conda and holoviz.

I an trying to install the excellent holoviz tutorial following:

I have first installed the latest miniconda in an osboxes VM:

bash Miniconda3-py310_22.11.1-1-Linux-x86_64.sh

Then I have run the usual commands:

conda create -n project “anaconda-project>=0.11”
conda activate project
anaconda-project download pyviz/holoviz_tutorial
cd holoviz_tutorial
anaconda-project run jupyter notebook

The last command fails with this (long) log:

Am i missing something, or there’s some issue with the tutorial “installer” ?

Thanks in advance!

This is related to the last week’s change in going from master to main in branch naming.

Go into the anaconda-project.yml and change the URL on this line:

  DATA_3:
    url: https://raw.githubusercontent.com/holoviz/holoviz/main/examples/assets/usgs_logo.png
