Encountering invalid git HEAD (reference 'refs/heads/master' not found) Error with pysr in Python

[spellbookrz]

Hello,
I am encountering an issue with the pysr library in Python where it throws an error invalid git HEAD (reference 'refs/heads/master' not found) when trying to call Julia code. This issue arises when pysr attempts to add certain Julia packages as dependencies.

Environment:

Python Version: 3.9.18
Julia Version: 1.9.4
Operating System: Windows 10
pysr Version: 0.16.3

Steps Already Taken:
Updating Julia Package Registry: Ran Pkg.update() in Julia REPL, which completed without indicating any changes needed.
Installing Dependencies in Julia: Successfully installed SymbolicRegression and ClusterManagers in Julia using Pkg.add(). No changes were indicated, suggesting these packages were already installed and up-to-date.
Ensuring Correct Julia Environment in Python: Tried setting the Julia environment in Python to ensure pysr is using the same environment where the packages were installed.
Reinstalling pysr: Attempted uninstalling and reinstalling pysr in Python to ensure the latest version.
Current Issue:
Despite these steps, when running pysr.install() in Python, the error julia.core.JuliaError: Exception 'invalid git HEAD (reference 'refs/heads/master' not found)' persists. This issue seems to occur when pysr tries to add its Julia dependencies.

Seeking Assistance:
I am looking for guidance or suggestions to resolve this issue. Thank you in advance for your time and assistance!

Maybe try doing the dependency install manually from the command line? Like this:

PYSR_VERSION=0.16.3
SRJL_VERSION=0.22.4  # Note this must be updated when PySR version is changed. See `version.py`
julia --project="@pysr-${PYSR_VERSION}" -e "using Pkg; pkg\"add PyCall ClusterManagers SymbolicRegression@${SRJL_VERSION}\""

and then just use PySR normally (without doing the python -m pysr install, as we did that above)

Thank you for your reply! I have done the steps as you said and it can now work normally!
