3. sudo docker build -t droidmind:latest .
4. sudo docker run -d -p 4256:4256 -e DROIDMIND_TRANSPORT=sse --name droidmind-server droidmind:latest

   I got error log like this:

Traceback (most recent call last):
  File "/opt/venv/bin/droidmind", line 3, in <module>
    from droidmind.server import main
