So, all in all, if I try to install Numpy, SciPy, pandas or any related libraries via pip I see several issues, no AIX version written (somewhere?) for Python 3.8, as well as pip addresses to mkl_rt, which is not found in the path.

I am trying to use python3.8 as a system interpreter and pip version: pip 19.2.3 I don't want to use conda. I am trying to test it using my system. What can I do?

What issues to you see?

What operating system and version are you on?

How did you install Python?

Note that Python 3.8 is still in beta and therefore a lot of 3th party libraries do no yet have binary wheels available. You therefore likely need a compiler to install Numpy and related libraries.

1) The OS: Mojave 10.14.6
2) Python is currently here: /usr/local/bin/python
3)Pip is here: /usr/local/bin/pip Here is pip -V: pip 19.2.3 from /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/pip (python 3.8)
4)I know it’s in beta, but I am trying to report the issues, which I find wrong
5) pip install <pkg> doesn’t work
6) If I install manually, I can install the libs:
	$ pip download <somewhat>
	$ cd somewhat
	$ python setup.py build
	$ python setup.py install

And in that case everything works, I can see the libs installed in my PyCharm app as well.

And I can run simple code in PyCharm with given Python and Pip, if I install the libs manually.

However, everything must work with just pip install <somewhat>, that’s why I am reporting.

Thx

Thanks for the update.

What's the error message you get when using pip to install?

That's huge, so I am attaching it in a separate file

There are known Cython-related issues with the latest NumPy *release* and Python 3.8, due to a signature change in PyCode_New. But those issues are already fixed in NumPy master. `pip install numpy` fails for me in a Python 3.8b4 venv, but `pip install git+https://github.com/numpy/numpy.git` works.

But none of this indicates a bug in core Python, as far as I know.

I forgot to include the NumPy issue link: https://github.com/numpy/numpy/issues/14403 (and other similar issues).

The pip error output you posted looks like the same issue to me.

At the end of each error log, there is a message stating different python versions (up to 3.7) and AIX. However, there is no python3.8 + AIX, and there is no corresponding dependency:

ERROR: Command errored out with exit status 2:

Thx for the link. Btw, I have tried: pip install git+https://github.com/numpy/numpy.git <git+https://github.com/numpy/numpy.git> That doesn’t work for me. The only way I can install somewhat is downloading the package, building and installing it.

Ana,

The error in "piperroroutput.txt" points to the issue Mark mentioned in msg351131: the current release of Numpy is not compatible with Python 3.8, but the tip of the tree on GitHub is.

I can install Numpy from the repository:

$ python --version
Python 3.8.0b4

I propose closing this issue as a 3th-party issue. This should resolve itself with the next release of Numpy.
