Reproduce the issue with visualdl --host 0.0.0.0 --port 8080 in the stated Docker environment. Start at visualdl/server/lib.py:585 and visualdl/reader/reader.py:100, where the traceback reports the missing _model attribute. Done means the page loads without the internal server error and the reported interface problem is resolved.
