The conflict is caused by:
pymc 5.20.1 depends on pytensor<2.28 and >=2.26.1
pymc 5.20.0 depends on pytensor<2.27 and >=2.26.1
pymc 5.19.1 depends on pytensor<2.27 and >=2.26.1
pymc 5.19.0 depends on pytensor<2.27 and >=2.26.1
pymc 5.18.2 depends on pytensor<2.27 and >=2.26.1
pymc 5.18.1 depends on pytensor<2.27 and >=2.26.1
pymc 5.18.0 depends on pytensor<2.26 and >=2.25.1
pymc 5.17.0 depends on pytensor<2.26 and >=2.25.1
pymc 5.16.2 depends on pytensor<2.26 and >=2.25.1

To fix this you could try to:

  1. loosen the range of package versions you’ve specified
  2. remove package versions to allow pip to attempt to solve the dependency conflict

Hi
I am trying to install Bart 0.9 package but getting this error that I think are related to pytensor.
Need suggestions

According to the messages Bart requires PyMC < 5.20

Thanks… I am now able to work but I have to downgrade…
Python 3.11
Pytensor 2.26.4
Pymc 5.15.1
Pymc-Bart 0.6.

Thanks for guiding

CC @aloctavodia can we lift the pin?

Done it! @Saurav_Rukhaiyar The last version of pymc-bart (0.9.1) is available from pypi, and soon it will also be available from conda-forge.

Hi…

Thanks for the help. However while running the code as in “Modeling Heteroscedasticity with BART — PyMC-BART”, I have observed very slow sampling i.e. at 10s/draw taking as much as 8 hrs.

I have not observed such slow sampling previously but now all models are sampling very slowly.
Suggestions will be appreciated
