ModuleNotFoundError: No module named 'sklearn.svm.classes' about construe

Hello,

I'm sorry you are having trouble with the environment. We have recently updated the .yml file to avoid cross-platform issues, so please try to install it again. Otherwise, to avoid the mentioned problem you should install a version of scikit-learn <= 0.22.1.

Please let me know if this worked for you.

You suggestion has been helpful.

I have built new conda environment, installed python=3.8, cython=0.28.5 to be able to install scikit-learn=0.22.1. Afterwards did conda env update from environment.yml and then compiled "construe.utils.signal_processing.dtw package" as you suggested in Known Issues. I have successfully managed to run run_example.sh!

I have also installed wfdb software package but I think I have done something wrong because when I run "python3 construe_ecg.py -r 100" it returnes:

init: can't open header for record 100
Traceback (most recent call last):
File "construe_ecg.py", line 123, in

raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError: Command '['wfdbdesc', '100']' returned non-zero exit status 2.

Hope that you can help me with that and thank you for your respond.

Hello,

It seems the problem is that the WFDB software is not able to read the record named '100'. The simplest solution is to copy the record (.hea and .dat files) to the same folder where you are running the script. Another solution is to modify the WFDB environment variable to point to the folder where the records are saved.

Thank you for the answer. I have successfully resolved this issue regarding the installation process! Now, I had tried to load my signal using wrsamp function to get .hea and .dat files, I have set the sampling frequency and multiplied the signal and error I get is:

File "construe_ecg.py", line 162, in
result = process_record_rhythm(rname, annots, args.tfactor,
File "./Desktop/Python/EKG_projekt/construe-public/record_processing.py", line 424, in process_record_rhythm
IN.set_record(path, ann)
File "./Desktop/Python/EKG_projekt/construe-public/construe/acquisition/record_acquisition.py", line 51, in set_record
_REC = load_MIT_record(record, physical_units)
File "./Desktop/Python/EKG_projekt/construe-public/construe/utils/MIT/record_reader.py", line 98, in load_MIT_record
raise ValueError('None of the signals in the {0} record is '
ValueError: None of the signals in the dataOut record is recognizable as an ECG signal

I manage to load the record and plot the signal, still it unrecognizible to this app, do you have any suggestions?
