Bug description:
When profiling a script that does not produce HTML output, the following warning is displayed:
Warning: No functions found in profiling data. Check if sampling captured any data.
However, when the --browser option is specified, the program still attempts to open the output file in a browser.
./python -m profiling.sampling run --flamegraph --browser script.py
# script.py
print("hello world")Suggested Fix
