I download parameters.yml from this task:
https://treeherder.mozilla.org/#/jobs?repo=try&author=[e-mail]&filter-tier=1&filter-tier=2&filter-tier=3&fromchange=2d3e7371d9f76a51a9f24b4213a5f52cf7f7abc7&selectedJob=33527056

then running mach taskgraph, I get this error:

I think it's leftover `.pyc` files.  Run `find . -name '*.pyc' -delete`.

ok, this works, bummer I didn't catch that.

I thought mach had protections against stray .pyc's, but I guess not.
