Potential problems with scipy v1.5.0 #2

Open mriener opened 4 years ago

mriener commented 4 years ago

It seems that upgrading to newer versions of scipy (>= v1.5.0) may cause an error as discussed here.

The workaround for now is to downgrade scipy to a previous version (v1.4.1 is tested and known to work).

I ran the demo programs (Tutorial_example-GRS.ipynb and Tutorial_decompose_single_spectrum.ipynb) with scipy v1.6.0 under python v3.8.7 without any problem.

I met this problem just yesterday. When using Scipy v1.5.4/ Python 3.6, Optimize raises "ValueError: x0 violates bound constraints" in Tutorial_example step 1. After I changed to v1.4.1 , no Error appeared.

Emmm, if I read this issue earlier, I won't get trouble with this hhhh.

Hi Chen,

It works with a more recent configuration for me : Python 3.8.7, scipy 1.6.0, numpy 1.19.5, and lmfit 1.0.1
