Review comment:
Can you modulize the test code? For example:
```python
def check_slice_partial_shape_infer(data, begin, end, step,
expected_out_shape):
out = mx.sym.slice(data, begin, end, step)
assert out.infer_shape_partial()[1][0] == expected_out_shape
check_slice_partial_shape_infer(var1, (None, None), (None, 10), None, (0,
10))
...
```
