vispr is broken

[Xin Belter]

I am following the nature protocols article of “Integrative analysis of pooled CRISPR genetic screens using MAGeCKFlute“. When I run the command on

step 7: Processing of CRISPR screen data with MAGeCK or MAGeCK-VISPR,

‌ (B) Process CRISPR screen data with MAGeCK-VISPR,

‌ (vii) (Optional) Visualize the results with VISPR

$vispr server results/*.vispr.yaml

I got the following error information:

I use Ubuntu 18.04, and Python 3.6 in miniconda3.
