Im trying to install the project with:
pip3 install barectf
and receive the error:

This seems to be caused by an incompatibility between PyYAML and the latest version of Cython (they recently bumped the major to 3).
The merged fix is to continue to require an older version of Cython as such:
[build-system]
requires = ["setuptools", "wheel", "Cython<3.0"]
until we can rewrite the extension build to eliminate all the ancient deprecated distutils magic
I believe this fix is part of the PyYAML 6.0.1 release, but barectf requires:
pyyaml = '^5.3'
I'll see if the project can accept and work with PyYAML 6.0.
In the meantime, you may force pip3 to use an older of Cython yourself:
$ echo 'Cython<3' > constraint.txt
$ PIP_CONSTRAINT=constraint.txt pip3 install barectf
Tell me if this helps.

this way is working:
echo 'Cython<3' > constraint.txt
PIP_CONSTRAINT=constraint.txt pip3 install barectf
This is not completed, I wrote above:

Keep this open.

Any updates on this one? Another problem I see is that the barectf requires old jsonchema which easily conflicts with other packages. So when installing the barectf, I see message to require jsonchema between 3.2 and 4.0
Collecting jsonschema<4.0,>=3.2 (from barectf)
Using cached jsonschema-3.2.0-py2.py3-none-any.whl.metadata (7.8 kB)
And then when installing jubyperlab-server, it requires newer jsonchema
jupyterlab-server 2.27.2 requires jsonschema>=4.18.0, but you have jsonschema 3.2.0 which is incompatible.
