Import errors when using the docker container

[heringerp]

I built the docker container and tried using it interactively but for the scripts odgi_to_rdf.py and sparql_odgi.py I get the following import error:

root@9580c13cbb68:/spodgi# odgi_to_rdf.py
Traceback (most recent call last):
  File "/usr/bin/odgi_to_rdf.py", line 3, in <module>
    import rdflib
  File "/usr/local/lib/python3.7/dist-packages/rdflib-7.0.0-py3.7.egg/rdflib/__init__.py", line 47, in <module>
    from importlib import metadata
ImportError: cannot import name 'metadata' from 'importlib' (/usr/lib/python3.7/importlib/__init__.py)

For the sparql_server.py script I got a different ImportError:

root@9580c13cbb68:/spodgi# ./sparql_server.py
Traceback (most recent call last):
  File "./sparql_server.py", line 2, in <module>

AttributeError: module 'typing' has no attribute 'Literal'

Both of these issues seem to come from the fact that the docker container has Python 3.7 installed, but rdflib 7.0.0 and flask 3.0.2 require Python 3.8.
