Large Siegfried CSV causing create_html_report function to break? #71
Description
I have a Siegfried CSV with 1,794,798 rows; When attempting to create a Brunnhilde HTML report based on the CSV input, the script fails.
I input the following:
brunnhilde.py --csv path/to/csv path/to/input_directory path/to/output_directory
The output I receive is as follows:
Traceback (most recent call last):
File "/opt/homebrew/bin/brunnhilde.py", line 1393, in <module>
main()
File "/opt/homebrew/bin/brunnhilde.py", line 1367, in main
process_content(
File "/opt/homebrew/bin/brunnhilde.py", line 956, in process_content
create_html_report(
File "/opt/homebrew/bin/brunnhilde.py", line 392, in create_html_report
begin_date = min(years, key=float)
^^^^^^^^^^^^^^^^^^^^^
ValueError: could not convert string to float: ''
Can I create a report using a large dataset such as the above? I would greatly appreciate any advice you could provide.
Many thanks,
Niamh
