If I upgrade numpy to 1.26.1 this error goes away.

Hi @lucask07,

Thank you for bringing this issue to our attention. The problem is caused by the dependency installation sequence. In the previous dependency settings, numpy >= 1.26.0 was installed first, but scipy ~= 1.9.1 would downgrade numpy to numpy < 1.25.0, >= 1.18.5.

To resolve this conflict, we have updated our requirements as follows:

• numpy ~= 1.26.0
• scipy ~= 1.11.0 (numpy < 1.28.0, >= 1.21.6)

We appreciate your attention to detail. If you have any further concerns or suggestions, please don't hesitate to let us know.

You can find more details about the update in this issue: #118

Best regards, Haowen 'John' Wei & PhysioLabXR Team"
