I have ValueError in NumPy

Question

input code:

randomlabel = [(random.randint(1,10),i) for i in geneex]
sortlabel = sorted(randomlabel)
store = {}
for i,j in sortlabel:
store.setdefault(i,[])

for i,j in sortlabel:
store[i].append(j)
print store

I got the rather cryptic error message

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

I can't tell what your problem is exactly from the code in your question above but what it means is that you are trying to do something along the lines of array == True whereas you should check either if any or if all elements are True explicitly. — sshashank124

Here the array comparison returns the boolean expression.

The Methods any() and all() reduce values over the array.

It would work fine if you replace the code with np.allclose()

Please have a look here ..It would help you out
