KWANT installation failure
Hi, I've tried several methods to mitigate this, but am unable to determine the root cause. pip install kwant fails on a new install of ubuntu. I have an ARM cpu which I believe should be compatible, however, I always get the following error. Thanks for any help!

Hi Gavin, Thanks for reporting this problem. I can reproduce it in an empy venv on my amd64 machine. The problem seems related to the latest NumPy version 2 which introduces breaking changes. If you can live without NumPy 2, please try out the following: pip uninstall numpy pip install ’numpy<2’ pip install kwant The above works for me in the same venv that otherwise produces the same error that you see. Please let us know if this workaround works for you as well. (Obviously a proper solution is needed. I’ll have a look into this.) Cheers Christoph
Dear Kwant friend, Recently, I have faced the same failure. I am trying afresh. Thanks.
