Dear sepal user,
as a temporary fix you could run pip install --user numpy==1.20.
I am working right now on a new version, which will fix those issues (i.e. using a dedicated environment). But you will still need a couple of days of patience.
However, if you have ideas how to improve, please use github issues or the forum here to tell us. We'll do our best to implement whatever is possible and relevant.
Best,
Andreas from SEPAL team
