 ```
 
+Since eccodes version 2.37.0, the eccodes binaries are shipped with the python binary, which can
+lead to some issues, especially if the locally installed stack of the software is executed. To
+overcome this, export the following environment variable (this will use the locally installed version
+of eccodes):
+
+```bash
+export ECCODES_PYTHON_USE_FINDLIBS=1
+```
+
+Other options can be found on the corresponding eccodes page of pypi:
+[Eccodes - Pypi](https://pypi.org/project/eccodes/)
