Unable to install guidedlda

[lamanamulaffer]

Hi, I'm trying to install guidedlda. I don't face any issues when using pip3 install guidedlda, however when I use import guidedlda I get an error message stating: ModuleNotFoundError: No module named 'guided._guidedlda'. When I try to install the other way, once I am in the GuidedLDA folder, I am unable to run build_dist.sh. The error I get is build_dist.sh: 3: set: Illegal option -o pipefail.

I'm running my code on Ubuntu 18.04.3 LTS, Intel Core i7-8700 CPU @ 3.20 GHz x 12, with GNOME 3.28.2. OS type 64-bit.

Any help will be appreciated - thanks in advance!
