I have multiple 2-D arrays as defined below:
a=[[4,6],[7,8],[9,10]]
I want to create a separate array(1-D) that takes the maximum number between the two elements in the array above. The solution should look like the below:
a=[6,8,10]
Any suggestions would be helpful. Thank you.
You could do it with list comprehension. Something like:
[np.max(l) for l in a]
Hi Jamie Wallis ,
Below is my actual dataset:
[3.06268544e-06, 9.99986887e-01], [9.54112887e-01, 7.73828626e-02], [9.88659620e-01, 1.66081488e-02], [5.52724719e-01, 5.17855644e-01], [7.01309919e-01, 2.87165940e-01], [9.94668126e-01, 9.48202610e-03], [9.91930544e-01, 1.50875747e-02], [3.17848325e-02, 9.65642691e-01], [2.90282569e-05, 9.99935508e-01], [2.84539819e-01, 8.28208566e-01]], dtype=float32)
I wanted to take the maximum of the two elements in the array and create a separate array(1-D) for the new values:
I tried but I get the following error message:
TypeError Traceback (most recent call last) in ----> 1 b = [max(elem) for elem in y_pred] 2 print(b) in (.0) ----> 1 b = [max(elem) for elem in y_pred] 2 print(b) TypeError: 'numpy.bool_' object is not iterable
You can try to delete ", dtype=float32)" in last part of dataset, then the np.max will work.
