I am trying to run the single cell clustering notebook locally in genepattern/genepattern-notebook:19.09.1. When the first cell with a UIBuilder auto-runs, I get this error:

The notebook runs fine on the public notebook server. I'm not sure what image version is running on the public server, but I did notice that my local image has nbtools==19.09 and the production notebook as nbtools==19.07.4.

Some light googling seems to indicate that otherwise nonsensical AttributeErrors can be caused by self-referential imports in some cases, and I did notice this line in a recent commit, maybe the issue is related to that?

Hi , I am using the nbtools framework . I want to ask a couple of things like :

1. The tools I create are temporary. When I open the notebook again they disappear. So can u tell me a way to make them permanent ?
2. I want to ship some tools default when the user opens the notebook, default tools should be available .. How can I achieve this?

PS: Thanks in advance

HI , I have been using nbtool framework for python3. I want to use it for the python2 support also.

I have tried installing nbtools in python2 by this command : pip2 install nbtools .
But when running any widget builder getting couple of errors for libraries that are in python3 like inspect.signature.

For some I have installed a backward compatbility like for inspect.signature I have installed funcsigs and use it. But getting another errors like for 'qualname' [ in init method of Class UIBuilder on line self.name = custom_name or function_or_method.__qualname__]

PS : Anyone can help me out this
THanks in advance

I was wondering does nbtools provide something for file download also similar to file upload ?
