ERROR: Failed to Installing pendulum (2.1.2)

[ITHwang]

Hi, I'm applying alignai sdk (0.2.1) but I met an issue below when installing pendulum (2.1.2).

• MacOS M3 Pro, sonoma 14.1
• Poetry 1.8.3
• Python 3.12

It seems to me that python 3.12 is not compatible with pendulum 2.1.2, but with ^3.0.0.
In python 3.11 both the alignai sdk and the pendulum are successfully installed.

Note: This error originates from the build backend, and is likely not a problem with poetry but with pendulum (2.1.2) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "pendulum (==2.1.2)"'.

@ITHwang Thanks for your report. I'm handling this on PR #10.

Fix released with version 0.3.0 @ITHwang
Align AI Python SDK does not depends on pendulum anymore.
