IndexError: index 11 is out of bounds for axis 0 with size 11

The actual error is not with axis 0, but axis 3.

error message:
    168                     if iJ>=9:
    169                         print(iE,iE0,iEtemp,iJ,li,lf,mlf+lf)
--> 170                     SS[iEtemp][iJ][li][lf][mlf+lf]= FF(jf,mf,lf,mlf,ji,mi,li,J)*SJ[iCh][jCh]
    171 
    172                 sumSJ1 += np.abs(SJ0[iCh][jCh])**2

IndexError: index 11 is out of bounds for axis 0 with size 11

Please include a sample script to reproduce the program along with a description of why you think it's an error in CPython. This seems to be a custom exception raised by a library.

This is a simple test:

test=np.zeros((2,3,4))
print(test[1][3][1])

IndexError                                Traceback (most recent call last)
<ipython-input-13-61c3cf4c90fc> in <module>
      1 test=np.zeros((2,3,4))
----> 2 print(test[1][3][1])

IndexError: index 3 is out of bounds for axis 0 with size 3

This is a numpy issue, you will need to report it to the numpy developers. But first you need to check that it really is a bug. What makes you think it is a bug? In your example, index 3 looks out of bounds to me. Remember that indexes start at 0, not 1.

In any case, this has nothing to do with us, numpy is an independent project, you will need to report it to them.

This is not a bug (and if it were you would have to report to numpy, not cpython).

Consider:

>>> import numpy
>>> a = numpy.zeros((2,2,2))
>>> a[0,2]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: index 2 is out of bounds for axis 1 with size 2

This is probably the message you expect. However, if you write
>>> a[0][2]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: index 2 is out of bounds for axis 0 with size 2

you split the operation into two steps, and the second axis of a is effectively the first axis of a[0].

I believe it's a bug. The axis 0 is misleading.  However, it is a problem
for numpy developers. Thank you for your time.
