Arras : run.py requirements ?

[nyue]

I am following the documentations here

I have installed the required module via the following requirements.txt (so I can recreate the environment for future deployment)

tornado==5
requests==2

I am getting the follow errors. Are there additional module or more specific dependency I should be installing ?

(omr_venv) ubuntu@minicordmachine:/opt/MoonRay$ python -i /opt/MoonRay/installs/openmoonray/python/minicoord/run.py
Traceback (most recent call last):
  File "/opt/MoonRay/installs/openmoonray/python/minicoord/run.py", line 10, in <module>
    from coord_service import CoordService

    import tornado.web
  File "/opt/MoonRay/omr_venv/lib/python3.10/site-packages/tornado/web.py", line 87, in <module>

    class HTTPHeaders(collections.MutableMapping):

Kind regards

Answering my own question.

As I am testing with Ubuntu, which provides Python 3.10 as default, collections.MutableMapping has changed

To resolve my issue, I have upgraded to using Tornado v6 instead of v5
