Hi Facu, was that on a new conda environment? Have you also tried with the install.py script? Let's look at that together

[rodriguez-facundo]

Hi, yes it was a new env. Steps to reproduce:

• rm -rf ~/.jupyter
• conda create nwb python=3
• . activate nwb
• git clone -b git@github.com:tarelli/nwb-explorer.git nwb
• cd nwb/utilities
• python install.py
