python - I am getting an error, How can I solve this problem?

Question

#storage for particles
vels = np.zeros((NP,3))
      
for s in range (NP):    
    
    v1 = maxw1d(vth)
    v2 = maxw1d(vth)
    v3 = maxw1d(vth)+vdrift
    
    mag = np.sqrt(v1*v1+v2*v2+v3*v3)
    
    #bin result, add to nearest
    bin = np.floor((mag-bin_min)/dbin+0.5)
    if (bin<NUM_BINS):
        bins[bin] = bins[bin] + 1
.....................................................

bins[bin] = bins[bin] + 1

IndexError: only integers, slices (`:`), ellipsis (`...`), numpy.newaxis (`None`) and integer or boolean arrays are valid indices
