Hello,

We have installed AIX Toolbox's libgfortran, openblas and numpy. When I tried to install matplotlib 3.2.2, I got the following errors (not sure if the 2nd error was caused by 1st one). Please help:

" ImportError: Could not load module /opt/freeware/lib/libopenblas.a(libopenblas.so.0).
        Dependent module libgfortran.a(libgfortran.so.5) could not be loaded.
    Could not load module libgfortran.a(libgfortran.so.5).
    System error: No such file or directory

        Dependent module /opt/freeware/lib/libopenblas.a(libopenblas.so.0) could not be loaded."

    Importing the numpy C-extensions failed. This error can happen for many reasons, often due to issues with your setup or how NumPy was installed."

Thanks

From the error message, it looks like libgfortran.a(libgfortan.so.5) is not found by openblas library. Please check whether you have the proper libgfortran rpms installed. 
Check "rpm -qa | grep libgfortran"

You have just the meta-package "libgfortran-10-2.ppc" which only provides the symlinks. The actual files are provided by libgfortran10-<version>-<release> package.. You need to install that one.
You can get it from -->
             https://public.dhe.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc-7.3/gcc10/   (for AIX 7.3)
             https://public.dhe.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc-7.2/gcc10/   (for AIX 7.2)
             https://public.dhe.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc-7.1/gcc10/   (for AIX 7.1)

Hi Ayappan P,

Please find the command output:

Hi Ayappan P,

It works. Thanks. By the way, the building of matplotlib requires many packages from AIX Toolbox. I am wondering when the new AIX Toolbox + python 3.9.16 is available and we do upgrade, will those already installed packages be upgraded automatically?

Thanks

Mi

There are some steps that needs to be followed to smoothly migrate from python3.7 to python3.9. 
We will come up with a blog for that.
