[pyngl-talk] pyngl-talk Digest, Vol 145, Issue 6

[Kevin Hallock]

Hi Paul and Victor,

This is an issue that we are aware of. As Paul mentioned below, a solution to the existing issue with NCL should solve the problem for PyNGL as well.

The conda-forge project recently upgraded certain dependency packages; in particular, we’ve experienced problems getting the newest version of the HDF5 library to play nicely with a current-but-several-years-old HDFEOS5 library.

We will try to get a fix for this onto conda-forge as soon as possible, but unfortunately some conda-forge compatibility/dependency issues are out of our (NCAR’s) control.

I’m sorry for the inconvenience,
Kevin

I opened an issue with the NCL package maintainers here: https://github.com/conda-forge/ncl-feedstock/issues/26 <https://github.com/conda-forge/ncl-feedstock/issues/26>. You might like to follow that issue because, I think, the PyNGL install will work again when the NCL package is fixed.
