Installing pygrib

Installing pygrib from the conda-forge channel can be achieved by adding conda-forge to your channels with:

conda config --add channels conda-forge
conda config --set channel_priority strict

Once the conda-forge channel has been enabled, pygrib can be installed with conda:

conda install pygrib

or with mamba:

mamba install pygrib

It is possible to list all of the versions of pygrib available on your platform with conda:

conda search pygrib --channel conda-forge

or with mamba:

mamba search pygrib --channel conda-forge

Alternatively, mamba repoquery may provide more information:

# Search all versions available on your platform:
mamba repoquery search pygrib --channel conda-forge

# List packages depending on `pygrib`:
mamba repoquery whoneeds pygrib --channel conda-forge

# List dependencies of `pygrib`:
mamba repoquery depends pygrib --channel conda-forge

About conda-forge

conda-forge is a community-led conda channel of installable packages. In order to provide high-quality builds, the process has been automated into the conda-forge GitHub organization. The conda-forge organization contains one repository for each of the installable packages. Such a repository is known as a feedstock.

A feedstock is made up of a conda recipe (the instructions on what and how to build the package) and the necessary configurations for automatic building using freely available continuous integration services. Thanks to the awesome service provided by Azure, GitHub, CircleCI, AppVeyor, Drone, and TravisCI it is possible to build and upload installable packages to the conda-forge anaconda.org channel for Linux, Windows and OSX respectively.

To manage the continuous integration and simplify feedstock maintenance conda-smithy has been developed. Using the conda-forge.yml within this repository, it is possible to re-render all of this feedstock's supporting files (e.g. the CI configuration files) with conda smithy rerender.

For more information please check the conda-forge documentation.

Terminology

feedstock - the conda recipe (raw material), supporting scripts and CI configuration.

conda-smithy - the tool which helps orchestrate the feedstock. Its primary use is in the construction of the CI .yml files and simplify the management of many feedstocks.

conda-forge - the place where the feedstock and smithy live and work to produce the finished article (built conda distributions)

Updating pygrib-feedstock

If you would like to improve the pygrib recipe or build a new package version, please fork this repository and submit a PR. Upon submission, your changes will be run on the appropriate platforms to give the reviewer an opportunity to confirm that the changes result in a successful build. Once merged, the recipe will be re-built and uploaded automatically to the conda-forge channel, whereupon the built conda packages will be available for everybody to install and use from the conda-forge channel. Note that all branches in the conda-forge/pygrib-feedstock are immediately built and any created packages are uploaded, so PRs should be based on branches in forks and branches in the main repository should only be used to build distinct package versions.

In order to produce a uniquely identifiable distribution:

• If the version of a package is not being increased, please add or increase the build/number.
• If the version of a package is being increased, please remember to return the build/number back to 0.

pygrib-feedstock's Issues

Python 3

Need to enable Python 3 builds once ecmwf_grib is available on py3k. (conda-forge/ecmwf_grib-feedstock#1)

Re-build jpeg stack

After we added https://github.com/conda-forge/jpeg-feedstock we re-built

• conda-forge/jasper-feedstock#3
• https://github.com/conda-forge/ecmwf_grib-feedstock/pulls?q=is%3Apr+is%3Aclosed

And the CIs here should be green 😉

Installing pygrib with conda-forge

Hello, I am trying to install pygrib using this repository, and have followed the instructions given.

When I try to import the pygrib module in a script, I receive the following error:

ImportError: dlopen(/Users/Alex/miniconda2/lib/python2.7/site-packages/pygrib.so, 2): Library not loaded: @rpath/libjpeg.9.dylib
  Referenced from: /Users/Alex/miniconda2/lib/libgrib_api.dylib
  Reason: image not found

Is there something I am missing? My installation of conda could sometimes be a bit weird as I accidentally installed it using sudo and now everything requires sudo.

pygrib 2.0.2 on OSX, PY 3.5: missing libjpeg.9.dylib

Import of pygrib fails (first block below); I also note that libjpeg does not appear in the dependency list (second block below).

Cannot import pygrib

I have tried using 'conda install' to install pygrib. When I got to import pygrib, I get 'ImportError: libgrib_api.so.1: cannot open shared object file: No such file or directory'. I can see the 'libgrid_api.so' in my /lib, but no libgrib_api.so.1. I am on a Linux machine using python2.7.

More tests with real data

The GitHub repo has a sample data directory and it would be nice to choose one or two data files to use here and test the package against the CLI shipped (cnvgrib1to2, cnvgrib2to1, grib_list, and grib_repack).

I played with the idea and I got a few failures. Since I don't know the first thing about pygrib I hope someone that knows what s/he is doing tackles this.

Missing jpeg

I installed pygrib:

$ conda install -c conda-forge pygrib

I tested import:

import pygrib
Traceback (most recent call last):
File "", line 1, in
ImportError: libjpeg.so.9: cannot open shared object file: No such file or directory

I installed jpeg:

$ conda install -c conda-forge jpeg

Now all is well. Please add jpeg to dependencies :)

It looks like that error is somewhere in the combination of the cython wrapper for grib_api.h from pygrib, possibly the real copy of grib_api.h from eccodes, and the numpy+cython interface.

pygrib numpy dependency error

I had an "old" python 3.6 environment that I wanted to use pygrib on. I did conda install -c conda-forge pygrib and got:

The following NEW packages will be INSTALLED:

    ecmwf_grib: 1.26.0-0     conda-forge
    jasper:     1.900.1-4    conda-forge
    pygrib:     2.0.2-py36_3 conda-forge

I think did import pygrib in ipython and got:

In [1]: import pygrib
---------------------------------------------------------------------------
RuntimeError                              Traceback (most recent call last)
RuntimeError: module compiled against API version 0xb but this version of numpy is 0xa
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-6160c29be9fd> in <module>()
----> 1 import pygrib

I then fixed it by doing conda update numpy which gave me:

The following NEW packages will be INSTALLED:

    blas:     1.1-openblas       conda-forge
    openblas: 0.2.20-7           conda-forge

The following packages will be UPDATED:

    llvmlite: 0.17.0-py36_0                  --> 0.22.0-py36_0                 conda-forge
    numba:    0.32.0-np112py36_0             --> 0.37.0-np114py36h210bcc1_0               
    numpy:    1.12.1-py36_0                  --> 1.14.2-py36_blas_openblas_200 conda-forge [blas_openblas]
    scipy:    0.19.0-np112py36_0             --> 1.0.1-py36_blas_openblas_200  conda-forge [blas_openblas]

And everything worked after that (so far). Just wanted to document this in case there is something that can be put in the meta.yaml to force the numpy version build dependency.
