ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

Hello! After I install the idr-2.0.2 and run idr --samples tests/data/peak1 tests/data/peak2, the error comes:
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
How could I fix this? Wish your reply, thanks.

I have the same problem (Python 3.8.3).
The error message "ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()" means that you should not evaluate a numpy array in a Boolean context.

Below is how I fixed this issue:

1. edit line 415 in the file "idr-2.0.2/idr/idr.py". if localIDRs == None or IDRs == None: into if localIDRs.all() == None or IDRs.all() == None. After this change, if all the values in localIDRs and IDRs are None, then replace them with 1.
2. rerun python3 setup.py install

Test:
python3 ./idr-2.0.2/bin/idr --samples ./idr-2.0.2/tests/data/peak1 ./idr-2.0.2/tests/data/peak2 --plot

Screen output:

Initial parameter values: [0.10 1.00 0.20 0.50]
Final parameter values: [1.57 1.26 0.89 0.41]
Number of reported peaks - 50537/50537 (100.0%)

Number of peaks passing IDR cutoff of 0.05 - 12748/50537 (25.2%)

When I re-install the latest version idr-2.0.3, I solved this problem.
