I've repeated all your steps and found that conda forces to install psycopg2-binary==2.9.1 instead of our dependency psycopg2==2.9.5 (https://github.com/heartexlabs/label-studio/blob/ls-release/1.7.2/deploy/requirements.txt#L50):

...

Successfully built psycopg2-binary

But I found a workaround:

conda install psycopg2

This will install psycopg2-2.9.3 which will unblock the startup of label-studio

[EnlNovius]

I encountered the same problem recently and got around it by installing libpq in conda before installing label-studio.

conda create -n label-studio python=3.9
conda activate label-studio
conda install -c anaconda libpq
pip install -U label-studio

This issue will be fixed in 1.7.3 release coming soon.

Another thing you can try:

conda install psycopg2

[17bryen]

For anyone else still getting this error, I had to force reinstall in order to get the correct version of psycopg2-binary:
pip install psycopg2-binary --force-reinstall

[robb666]

I'm experiencing this problem with pip.

When pip install psycopg2-binary --force-reinstall I get:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
label-studio 1.7.1 requires psycopg2-binary==2.9.1, but you have psycopg2-binary 2.9.6 which is incompatible.

And I am back to;

Hi I've encountered the same problem by following the official install guide with anaconda.
After reinstall psycopg2, the problem was still there. Then I found that the root cause is conda install Python3.11 automatically, while label-studio is only supported under Python3.9. So the problem is solved by install Python3.9 first, then install label-studio 1.8.

@hxuaj how to install label-studio 1.8 ? is the default version ? in this case should we run this: conda install psycopg2 # required for LS 1.7.2 only
