Cannot install the package

Hello. I am not able to install the package right now.

Steps/code to reproduce: On the terminal, I am running

pip install sysidentpy

and I get

Hello. Try to update your numpy package before install sysidentpy.

pip install -U numpy

Hi @renard162 . Tried but numpy 1.19.4 is not working in windows. After I updated I could not install sysidentpy and also could not import numpy. After updating I run

import numpy

and I get

** On entry to DGEBAL parameter number  3 had an illegal value
 ** On entry to DGEHRD  parameter number  2 had an illegal value
 ** On entry to DORGHR DORGQR parameter number  2 had an illegal value

If I run

pip install sysidentpy

I get the exact same error described in my previous comment.

Thanks in advance.

Hi @neylsoncrepalde ! There are some issues with numpy 1.19.4 when using python 3.9. The error you got is a numpy issue. Could you check what is your python version again just to make sure? I don't know if numpy 1.19.4 is having issues with python 3.8.

Besides, matplotlib do not have wheels for python 3.9 yet, so you will have a problem when you try to install sysidentpy in python 3.9 env because the two packages we are depending on are having issues with python 3.9.

I suggest you to install python 3.8 and numpy 1.19.3 for now (everything is working using those versions).

Let me know if this workaround solves your problem.

Hi @neylsoncrepalde. I checked here with numpy 1.19.3 and python 3.8 and everything is ok, As I said, numpy 1.19.4 is causing the issue you described. Refer to the link below for more details:

I'm closing this issue for now, but if the suggested steps do not work for you, just let us know.
