caveclient > 5.15.2 crashes microns tutorial

[jakobtroidl]

Description
I think caveclient version > 5.15.2 introduces a bug in the microns interface tutorial.

To Reproduce

pip install caveclient==5.15.2 # works
pip install caveclient==5.17.2 # throw's an error (see attached)

import navis.interfaces.microns as mi
client = mi.get_cave_client(datastack='cortex65')
client.materialize.get_tables()

Traceback for cavclient==5.17.2 is

Thanks for the report, Jakob!

I hadn't looked at this dataset in a while but it seems the datastacks were updated: for the cortex65 it used to be just minnie65_public_v117 but there are now multiple versions, with minnie65_public_v661 being the latest.

>>> import navis.interfaces.microns as mi
>>> client = mi.get_cave_client(datastack='cortex65')
>>> sorted(client.info.get_datastacks())
['fanc_production_mar2021',
 'fanc_sandbox',
 'flywire_fafb_production',
 'flywire_fafb_public',
 'flywire_fafb_sandbox',
 'minnie35_public_v0',
 'minnie65_public',

 'minnie65_public_v343',
 'minnie65_public_v661',
 'minnie65_sandbox',
 'mrgd',
 'pinky_sandbox']

I will have to rework the functions to always use the latest but in the meantime, here is a workaround:

>>> import navis.interfaces.microns as mi
>>> client = mi.get_cave_client(datastack='minnie65_public_v661')
>>> client.materialize.get_tables()

Hi @schlegelp , a related question: I was not able to fetch a neuron from v661

`rid = 864691135162983725

n = mi.fetch_neurons(
rid, with_synapses=True, datastack='minnie65_public_v661'
)
n`

the message I got:

864691135162983725 generated an exception: GrapheneUnshardedMeshSource.get() got an unexpected keyword argument 'progress'

@wanqingy what version of cloudvolume are you on?

[wanqingy]

11.0.1

Hi @wanqingy. Your example works for me with navis 1.9.0 and cloud-volume 11.0.1 or 11.0.2. What version of navis are you on?

I should add though that it's currently failing if with_synapses=True but with a different error and that seems to be on the CAVE end.

@bdpedigo: for that datastack, client.materialize.synapse_table is pointing to "synapses_pni_2" which doesn't seem to exist for me. Consequently, client.materialize.synapse_query() is failing. Is that a configuration issue?

[wanqingy]

@schlegelp hi! Upgrading from navia 1.7.0 -> 1.9.0 solved the issue if with_synapses=False

@bdpedigo added an option to set materialization version in CAVEclient, so I normally just use

version = 661
datastack = 'minnie65_public'
client = CAVEclient(datastack,version=version)

[bdpedigo]

my understanding is that the 'minnie65_public_v661' syntax is no longer preferred; if I remember correctly, it is hitting a completely different version of the server but @fcollman correct me if I'm wrong. regardless I think providing a passthrough for setting a version of the client like Wan-Qing showed would be more sustainable going forward, and would let people specify arbitrary datastack versions (although, for just getting the mesh from a root ID, this shouldn't matter, but for getting synapses it will).

[schlegelp]

OK, I see. So minnie65_public is the preferred datastack and on top of that, the root ID you're querying is not current?

Our package for the FlyWire dataset - fafbseg - has a bunch of utility functions and guardrails to e.g. match root IDs to materializations. We don't provide the same functionality in the built-in microns interface at the moment but minimally we can provide the option to specify a materialization version and possibly some clever way to find a matching version by default.

I just made a new release. If you update navis to 1.9.1 this should just work:

>>> import navis.interfaces.microns as mi
>>> n = mi.fetch_neurons(864691135162983725, with_synapses=True, datastack='cortex65', materialization="auto")
>>> n[0].connectors.head()
          id        x       y        z type  size
0  299725236  1036344  786632   774680  pre  8704
1  332436677  1114904  828216   998200  pre  9088
2  197429586   799496  855720  1013280  pre  4288
3  292971356  1023800  805720   758760  pre  3952
4  330339468  1123520  804848   864360  pre  4612

1. datastack='cortex65' now correctly points to minnie65_public
2. mi.fetch_neurons() now also accepts a materialization parameter that lets you specify a version. It defaults to "auto" in which case it just tries to find the latest materialization in which your root ID(s) exist.

@schlegelp Thank you!
