When I try to import Faerun, I find a bug.

This seems to be caused by a wrong import of your latest version, from tmap.core import TMAPEmbedding,
I don't understand why this was inported, tmap seems to have no core or TMAPEmbedding.

I solved by downgrading to 0.4.0.
pip install faerun==0.4.0

However, I think you should fix this bug.
Thanks.

I installed tmap==1.2 and faerun==0.4.0 without any problems.
But I got next error

      4     dims = 512
----> 5     lf = tm.LSHForest(dims, 128, store=True)
      6 

AttributeError: module 'tmap' has no attribute 'LSHForest'

What is wrong? How can I fix it?

Hi @liudongliangHI, thanks for the info. I bumped faerun-python to version 0.4.2. This bug is now fixed. I introduced the bug because I'm testing a pip installable version of tmap (https://pypi.org/project/tmap-viz/).

Hey @meddwl, it's a bit tricky to say--it looks like the package didn't install correctly, could you share more details on how you install it? Did you use:

conda -n tmap-env -c tmap tmap

Alternatively, you could try it with the new "beta" pip package:

pip install tmap-viz

I have also found this problem before, and it seems that it can be solved by updating to the latest version.

pip install tmap-viz
