Re: Allow installation on buster of a package not supporting 3.7 (async/await syntax error when generating bytecode)

Just tried but it's not working:

I wrote:

dir|3.7-|/usr/lib/python3/dist-packages/tensorflow/

But installing the package gives:

Traceback (most recent call last):
   File "/usr/bin/py3compile", line 290, in <module>
     main()
   File "/usr/bin/py3compile", line 266, in main
     e_patterns = get_exclude_patterns()
   File "/usr/bin/py3compile", line 93, in get_exclude_patterns
     for type_, vers, dname, pattern in get_exclude_patterns_from_dir():
   File "/usr/share/python3/debpython/__init__.py", line 22, in __call__
     self.cache[key] = self.func(*args, **kwargs)
   File "/usr/bin/py3compile", line 68, in get_exclude_patterns_from_dir
     type_, vrange, dname, pattern = line.split('|', 3)
ValueError: not enough values to unpack (expected 4, got 3)

I'm wondering if the "dir" type is actually supported: "re" type 
contains the appropriate number of fields.

Regards, Adam.
