Message
An `axis` must be a non-negative integer or a tuple/list of non-negative integers, but got `{value}`.
Possible fix: count axes from 0 (negative axes are not supported).
({value} is a repr of the offending axis value, truncated to 80 characters)
Cause
The axis= argument of a reduction — jm.sum, jm.prod, jm.min, jm.max, or the corresponding .sum(), .prod(), .min(), .max() methods — is neither a non-negative integer nor a tuple/list of non-negative integers.
Floats, strings, and other objects trigger this error, and so do negative integers such as axis=-1: negative axes counting from the end are not supported.
A tuple or list containing any non-conforming element is rejected as a whole, with the whole container shown in the message.
Fix
Pass the axes as 0-based non-negative integer positions, either a single one or a tuple/list of them:
jm.sum(A, axis=0)
jm.sum(A, axis=(0, 2))
To address the last axis, write its explicit non-negative position instead of -1.
