[yt-users] Exporting notebooks

Hi, I’m getting a batch of errors (OK… 2) when using python notebooks with yt 3.0: (1) I’m trying to export my python notebook into something shareable (ideally a pdf document). However, when I click ‘Print Preview’ or ‘Download as—> html’ I get the error: No module named pygments.formatters tornado.access: [ERROR ] Is there something extra I need to add to the yt python install to get this working? This happens both on my linux workstation and my macbook when I try and run nbconvert. (2) when I try: ts = DatasetSeries([“DD0002/sbcool_0002”, “DD0010/sbcool_0010”]) I get the error NameError: name ‘DatasetSeries' is not defined is this something that slipped through being imported int yt 3?
