KeyError: '516' while running wfdb.rdrecord and wfdb.rdsamp

[svinnak2]

Hello,

I'm running below code and getting KeyError: '516'. No more information to debug the error. Could you please provide me some inputs to solve the error.

Start of Code

segment_names = ['83404654_0005', '82924339_0007'] segment_dirs = ['mimic4wdb/0.1.0/waves/p100/p10020306/83404654', 'mimic4wdb/0.1.0/waves/p101/p10126957/82924339']

rel_segment_n = 1 rel_segment_name = segment_names[rel_segment_n] rel_segment_dir = segment_dirs[rel_segment_n] print(f"Specified segment '{rel_segment_name}' in directory: '{rel_segment_dir}'")

sampfrom = fs start_seconds sampto = fs (start_seconds + n_seconds_to_load)

segment_data = wfdb.rdrecord(record_name=rel_segment_name, sampfrom=sampfrom, sampto=sampto, pn_dir=rel_segment_dir)

print(f"{n_seconds_to_load} seconds of data extracted from segment {rel_segment_name}")

End of Code

You're using an old version of wfdb. Please upgrade to the latest version (4.0.0).
