With more traceback: ```Python in ----> 1 vol[6300:6500, 20400:20600:, 14000] ~/.pyenv/versions/3.7.5/lib/python3.7/site-packages/cloudvolume/frontends/precomputed.py in __getitem__(self, slices) 526 requested_bbox = Bbox.from_slices(slices) 527 --> 528 img = self.download(requested_bbox, self.mip) 529 return img[::steps.x, ::steps.y, ::steps.z,...

I got it to work by manually setting the data_encoding: ```Python vol.scale['sharding']['data_encoding'] = 'raw' m = vol[6300:6500, 20400:20600:, 14000] ``` It is rather slow for a 200x200 cutout though: ```Python...

Yes something along those lines is what I had in mind. It boils down to a three-step process: 1. Associate synaptic connections with a node/vertex on the pre- and postsynaptic...

I've seen that issue. Will think about a way to catch this specific issue but in the meantime you could try to mock vispy before importing `navis`?

I finally had time to try this myself. This is a bit hacky it but it should let you import and work with navis (minus vispy plotting obviously): ```Python import...

I assume you're referring to the Janelia hemibrain dataset? As far as I know the neurotransmitter predictions aren't yet publicly available. Under the hood, `navis` uses [`neuprint-python`](https://github.com/connectome-neuprint/neuprint-python) to fetch data...

I fully agree. That said: the `BaseReader` class is already a pretty complex thing and I'm a bit reluctant to add to that. My suggested solution would still correctly check...

Ah good point! I didn't bother hunting for existing implementations for neuroglancer's "precomputed" format. I have independent functions in various other packages and this was actually my attempt at consolidating...

Oh, I see. We might be thinking of slightly different things here. I'm not at all opposed to adding it as a dependency but perhaps you can elaborate a bit...

This error originates from the `cloud-volume` package which `navis` uses to fetch meshes, etc. from MICRoNS datasets. It looks like it's failing to read the meta data when first initialising...
