The exactly same code on windows machine is running just fine, on both machines the input data are the same, and when I checked inside the scipy library, specifically https://github.com/scipy/scipy/blob/v1.4.1/scipy/optimize/lbfgsb.py#L49-L208.
all arrays seemed to have same data type, although there were both float32 and float64 types.
I'm using this library in following conda environment:

any help would be appreciated, I'm a bit lost in what can I do about this.
Is this some bad version of library, too new/too old? Or something else?
I assume it might be same issue as #99 .
