F-score, Precision, and Recall values

[ThomasL]

Did you use .numpy() twice?

    return f1.numpy(), precision.numpy(), recall.numpy()
 
f1, precision, recall = computeMetrics([1.0, 2.0, 3.0, 4.0], [1.1, 1.9, 3.2, 4.1])
 
print('metrics: ', f1.numpy(), precision.numpy(), recall.numpy())

AttributeError: 'numpy.float32' object has no attribute 'numpy'
means that the variables are already a numerical object that you can use/print directly
so delete the .numpy() or don´t use it twice on the same object.
