    The same error when I use python3_64. Everything is updated:

    # dnf clean all
35 files removed
# dnf -y update

    dnf & dnf modules are only 32-bit in AIX 7.1 & 7.2 ( because rpm is 32bit there) 
    So using the default python3 (which is 64bit) you can't import a 32bit module. 
    But you can do that with 32bit python "/opt/freeware/bin/python3_32". 
    In AIX 7.3 , rpm ,dnf & dnf modules are all 64bit. So you can import using the default 64bit python3.

    Thank you Ayappan! I thought python3 is 32-bit and python3_64 is 64-bit.
