Help installing pyqlib

I've made few attempts to install pyqlib using both pip install and build from source.

I use conda environments and tried with 3 different Python versions 3.8.15, 3.8.17 and 3.9.13.

The common issues encountered are:

• Using pip install pyqlib

Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement pyqlib (from versions: none)
ERROR: No matching distribution found for pyqlib

Same error when trying Jupyter Notes with Google Collab: https://github.com/microsoft/qlib/blob/main/examples/workflow_by_code.ipynb

This

• Install from source

3.9

ERROR:: Could not find a local HDF5 installation.
You may need to explicitly state where your local HDF5 headers and
library can be found by setting the HDF5_DIR environment

3.8
RuntimeError: Scikit-learn requires Python 3.9 or later. The current Python version is 3.8.15 installed

Any pointers would be great.

Start by reproducing the reported pip and source-install attempts with Python 3.8 and 3.9, including the Jupyter notebook environment. Compare the package availability, HDF5 detection, and scikit-learn version errors; done would mean identifying and documenting a supported installation path or correcting the installation requirements.
