Visualize the results doesn't work

I am trying to run

` poetry run python app.py --from-results-dir ..\..\..\ --port 7861
C:\Users\xiaosong\Documents\multi_instances\inference-benchmarker\extra\dashboard\parse_results.py:34: FutureWarning: The behavior of DataFrame concatenation with empty or all-NA entries is deprecated. In a future version, this will no longer exclude empty or all-NA columns when determining the result dtypes. To retain the old behavior, exclude the relevant entries before the concat operation.
df = pd.concat([df, df_tmp])

To create a public link, set `share=True` in `launch()`.`

But it just hangs there, and no progress.
