That is a problem when I try use add library numpy,pandas with python from 3.8 to 3.10. Whether we have any way to fix this problem?

import numpy as np

Unfortunately both numpy and pandas are C extension modules which are not supported. As for the System.MissingMemberException, the os.add_dll_directory method was only added in Python 3.8.

[chuongmep]

@slozier Whether we have any plan for that ? Because numpy and pandas is common library.

[slozier]

Unfortunately, no short term plans. There's the Ironclad project which I'd like to revive at some point, however there are still many core features that need to be implemented so I haven't time to look at it.

@slozier Could you update the IronClad for Ironpython3 status. It seems U have made lots of progress lately C Extension support through Ironclad for Ironpython3: March2023 Update

[slozier]

@GeorgeS2019 I am just playing around with it trying to get it to compile with the Python 3.4.4 codebase. Even if I do get it compiling I am not sure anything will work with it as there have been a number of core changes going from 2 to 3 that will likely require a lot of work. In any case, I do not have any sort of timeline for it...

@slozier ,

Thx for sharing.

Any chance of listing these challenges in concrete ways and outsource to others.

Thx for attempting this herculean task

[GeorgeS2019]

@slozier

The fact that Changes for Ironclad happens, means the attempt will continue.

Thanx

[GeorgeS2019]

Progress continue...update May 2033 😊
