Outdated pypi repository

[tiagoshibata]

Hi,

It seems that the pypi repo is a bit outdated. Building fails in Python 3, would you mind updating it?

Thanks!

I second this request. OpenEXR in Python 3 would be a lifesaver.

OpenEXR in Python 3 would be a lifesaver.

Of course having an updated PyPI package would be nice, but if you need to use it, it works when built from source.

PyPI package updated to 1.3, which builds/regresses under 2.6, 2.7, 3.2 and 3.5:

https://pypi.python.org/pypi/OpenEXR/1.3.0

Closing.

@jamesbowman I did pip3 install openexr but I get some weird errors. Am I supposed to do something else before running the pip command? I am using Python 3.5.2

[jamesbowman]

Yes, that should work. In fact I just did it and it succeeded.
What platform are you on? What are the specific errors?

~ $ sudo pip3 install openexr

@jamesbowman Here's shows what I get after pip3 install openexr:

@jamesbowman It seems that some other people have the same issues [1], [2]

Did you try pip3 install openexr in Ubuntu or Windows? I am using Ubuntu

[so-rose]

@Amir-Arsalan ImathBox.h is one of the C++ header files used to compile OpenEXR. These header files are (implicitly) a dependency of the Python bindings on Linux, where pip likes to recompile anything you pip install.

The error suggests that you perhaps don't have these OpenEXR development files installed. This is easy to do in Ubuntu: Try installing the package libopenexr-dev using apt, then rerunning pip install.

[tiagoshibata]

You are missing OpenEXR's headers. Install them and OpenEXR's libraries and the Python wrapper will compile.

Edit: @so-rose was a bit faster 😆

[Amir-Arsalan]

@so-rose @tiagoshibata Sorry maybe I should have mentioned that I did sudo apt-get install libopenexr-dev before doing pip3 install openexr but things still do not work. Could it be because libopenexr-dev works with Python 2?

[Amir-Arsalan]

I did a fresh Ubuntu install and things are fine now. I also had to do sudo pip install openexr otherwise I would get some other errors.

@jamesbowman The OpenEXR repo has had new commits in the past few months. I wonder, are you planning to update the pypi package in a soon future?

[jamesbowman]

Version 1.3.1 uploaded to PyPI. Closing.
