pandas fails to build (aware that this is not emzed2 !)

[lopippo]

Greetings,

on my Debian box, I am trying the setup.py install command.

That command elicits the download of a number of Python packages that are built "live".

There are a huge bunch of warnings, more or less critical in a number of packages. However, the first errors appear when building pandas (see below).

My question: did you already encounter these problems ?
What version of Python (2.7 or 3.x) should be used for building emzed2 ?

Thank you for your attention.

Hi, pandas dropped Python 2 support for a while and thus does not offer precompiled packages any more. This is one of the reasons why we started emzed 3.

I checked the repository at pypi.org and it seems that pandas 0.24.2 offers precompiled packages for linux. Can you thus try to run

$ pip install pandas==0.24.2

?

[lopippo]

And then change the requirement pandas<0.18 in setup.py, I gather ?

[lopippo]

Yes, that worked, going on...

[lopippo]

And now a HUGE amount of errors with calls to print missing parentheses around the arguments each time. I guess this will take some time to fix ?

[lopippo]

It is odd, because there we many such warnings, in reality, when building other installed packages. But this one is a real error:

File "/tmp/easy_install-w913ypqx/ipython-0.10/setup.py", line 55
print 'Unsupported operating system:',os.name

Can it be possible that ipython has such an error ?

[lopippo]

The setup.py file mentions ipython == 0.10, maybe I could try without the version limitation ?

[uweschmitt]

1. emzed2 is not Python 3 ready
2. You will encounter many other issues with PyQt and plotting libraries, this was already a problem on linux some years ago.
3. Do you have access to a windows machine? The installer we offer for windows should still work.

The setup.py file mentions ipython == 0.10, maybe I could try without the version limitation ?

you can try. but weaken the restricition. If you remove it you will get ipython 6 or 7 and these versions are very different.
