Installation fails if numpy is not already installed with python 3.8 about osqp-python

[bstellato]

pip wheels for python 3.8 are online! Could you please try to install it again?

Can confirm, still an issue with python3.8.

Simple way to reproduce:

Python 3.8

$ docker run --rm python:3.8 pip install "osqp<0.7.0,>=0.6.1"
Collecting osqp<0.7.0,>=0.6.1
  Downloading osqp-0.6.1.tar.gz (211 kB)

Python 3.7

$ docker run --rm python:3.7 pip install "osqp<0.7.0,>=0.6.1"
Collecting osqp<0.7.0,>=0.6.1

So apparently the problem is that there is no whl packaged for Python 3.8. docker run --rm python:3.7 pip install --no-binary :all: "osqp<0.7.0,>=0.6.1" fails with the same error as the Python 3.8 output above.

cvxpy has an upgrade issue to python3.8 because of this problem...

[bstellato]

Sorry about the delay, last months were not easy! I am trying to build the wheels for Python 3.8 here. I hope to have it in the next few days. We will have more releases with better deployment tools this summer.

Could you please try to install it again?

Yep, I can confirm it works now. thanks! 🙂

(for the record: tested with python 3.8.2 and pip 20.1)

[bstellato]

Awesome! Thanks for your patience. I will close the issue. Feel free to reopen it if you have any other problems.

Awesome! Thanks for your patience.

No worries ;) Thanks for taking the time to fix the issue
