Error installing numpy for pypy3

Question

Trying to install numpy for pypy3 on my MacBook, I receive an error.

Here are the instructions to install numpy.

git clone https://bitbucket.org/pypy/numpy.git
cd numpy
pypy3 setup.py install

But when I launch "pypy3 setup.py install, I receive this error message:

Running from numpy source directory.

Do you have an idea of what is the problem?

Answer 1

You're right...

Numpy is available only for Pypy 2.5.0, which is compatible with Python 2.7.

I actually use Python 3.4.2, so all my files are compatible with pypy3 and not pypy. I will do without numpy then... Hope they will manage to make it work for pypy3 in the next few months!

Answer 2

https://bitbucket.org/pypy/numpy - Have you verified with pypy that their version of numpy works with pypy3? A quick read of their site suggests it is still in the works.

For now, NumPyPy only works with Python 2, and is not complete. You may get warnings or NotImplemented errors. Please let us know if you get crashes or wrong results.
