Develop branch cannot work with Python 3.9

[dangokuson]

I'm using source on the develop branch and Python 3.9.x. However, I cannot successfully install the PycQED dependency defined in the requirements.txt file. The develop branch does not support Python 3.9.x right ?

[MiniSean]

The develop branch should support Python 3.9.x. Can you specify what problem you are running into?

@MiniSean Thanks!

Here is my environment:

• Apple Chip M2
• OSX Sonoma 14.x
• Python 3.9.1

I used this comment to install OpenQL: pip install qutechopenql@git+https://github.com/DiCarloLab-Delft/OpenQL@82a9881bdb2c2f2b0620c14c549c436f21d1607c. However, I encountered below problem:

How can I install OpenQL?

[MiniSean]

@dgks0n thanks for letting us know about this issue.

This requirement on a specific development version of qutech-openql is something we are trying to phase-out. Try pip install qutechopenql. Most of the common functionality in Pycqed is compatible with the public release of qutech-openql.

@MiniSean It seems it does not work on Apple Chip M2 (arm64). I tried this pip install qutechopenql:

ERROR: Could not find a version that satisfies the requirement qutechopenql (from versions: none)
ERROR: No matching distribution found for qutechopenql

Here is my environment:

• Apple Chip M2 (arm64)
• OSX Sonoma 14.x
• Python 3.9.1
