🐛 Uncaught exception GET

🐛 Bug

When trying to run the webapp with the example data, I have this error :

Uncaught exception GET

To reproduce

Follow README instructions : download example data and run :

python -m vizseq.server --port 9001 --data-root ./examples/data

The server starts fine, but when accessing the webapp at localhost:9001, I can only see 500: Internal Server Error.

Stack trace/error message

Expected Behavior

The webapp run normally.

I ran the app with debug mode (python -m vizseq.server --port 9001 --data-root ./examples/data --debug)

and when I accessed the webapp it gave me this Traceback :

Traceback (most recent call last):
File "/home/remondn/.venv/presum/lib/python3.6/site-packages/tornado/web.py", line 1590, in _execute
result = method(*self.path_args, **self.path_kwargs)

d for d in os.listdir(data_root)
FileNotFoundError: [Errno 2] No such file or directory: './examples/data'

It's because the data was downloaded in ./data/ and not ./examples/data/. Running the server again with the right path :

python -m vizseq.server --port 9001 --data-root ./data

works perfectly 😃

You might want to update README and change the data-root path, by default get_example_data.sh download the data to ./data and not ./examples/data.

Thanks for reporting this! I will fix the unzipping path in get_example_data.sh.
