installation--> import error

just tried pip installing into the open2c environment and am getting the following:

I went past the pydantic issues by using its last stable version v1.10.7
I guess it installs pydantic 2 because of the --pre flag in pip install

The higlass-python doesn't work for me still though...
There are no more errors, but it doesn't render even remote heatmaps

Yes, there seems to be an issue with the default HTML repr. I'll resolve this asap, but have limited time at the moment. As a workaround, you should be able to use the .widget() method to render the visualization as Jupyter Widget (instead of the default behavior).

import higlass as hg

# Remote data source (tileset)
tileset1 = hg.remote(
    uid="CQMd6V_cRw6iCI_-Unl3PQ",
    server="https://higlass.io/api/v1/",
    name="Rao et al. (2014) GM12878 MboI (allreps) 1kb",
)

# Local tileset
tileset2 = hg.cooler("../data/dataset.mcool")

# Create a `hg.HeatmapTrack` for each tileset
track1 = tileset1.track("heatmap")
track2 = tileset2.track("heatmap")

# Create two independent `hg.View`s, one for each heatmap
view1 = hg.view(track1, width=6)
view2 = hg.view(track2, width=6)

# Lock zoom & location for each `View`
view_lock = hg.lock(view1, view2)

# Concatenate views horizontally and apply synchronization lock
(view1 | view2).locks(view_lock).widget()

or

view1.widget()

.widget() works indeed ! Thank you !

[manzt]

Published a new release candidate which should fix the rendering issue (without .widget()). I think the biggest priority right now is trying to resolve cooler compatibility clodius (especially if you're using cooltools).

[sergpolly]

yez ! I've actually just tried to see if I can help with that higlass/clodius#150 ...

Since that issue, I've managed to run clodius tests and see tiles/coolper.py failures - that's a start ...

Unfortunately I don't know much about tiles-serving logic inside, so if you know what needs to be fixed even more specifically - that would help !
