Hello all,

I am new to using SITK and I’m trying to follow the Environment setup tutorial but when I try to run the following “from download data import fetch\_data, fetch\_data\_all” I get an error saying: “No module named ‘download data’. I checked the github repository and downloaddata seems to be one of the modules of SITK so I’m not sure what the issue is? I believe I need this to be able to read my png image properly. Can someone please help me with this?

The version of SITK I am using is: 2.2.1 (ITK 5.3)

downloaddata.py is from the SimpleITK notebooks. Here’s where it is:
