Error in installing OpenEXR

[siddas27]

I tried installing OpenEXR on Mac inside conda env by

pip install OpenEXR

Here is the output

Pypi has a link to the py openexr project, here: https://pypi.org/project/OpenEXR/ It would be best to open an issue with the project owner, as it is an independent effort, not part of the OpenEXR project itself.

I encountered the same problem, wondering how you managed to solve it.

On @jamesbowman's repo, where development of openexrpython occurs, it appears this issue, of not finding <ImathBox.h> has been resolved:
