No module named 'numpy.lib.arrayterator'

[Jim Fluke]

Hello,

I have been seeing this error message recently - just for the last two weeks. Here is the code:

import os
from pydap.client import open_url

When I try to run this, I get:

Traceback (most recent call last):
 File "/app/opendap_pydap.py", line 2, in <module>
   from pydap.client import open_url
 File "/opt/conda/lib/python3.12/site-packages/pydap/client.py", line 53, in <module>
   from .handlers.dap import DAPHandler, unpack_data, StreamReader
 File "/opt/conda/lib/python3.12/site-packages/pydap/handlers/dap.py", line 32, in <module>
   from .lib import ConstraintExpression, BaseHandler, IterData
 File "/opt/conda/lib/python3.12/site-packages/pydap/handlers/lib.py", line 21, in <module>
   from numpy.lib.arrayterator import Arrayterator
ModuleNotFoundError: No module named 'numpy.lib.arrayterator'

It seems like the import statement in lib.py ought to be:

from numpy.lib import Arrayterator

Any help would be greatly appreciated.

Thanks,

Jim

I think so, yes -- looks like that may have changed in numpy 2.0:

https://numpy.org/doc/stable/numpy_2_0_migration_guide.html#numpy-lib-namespace

you may need to post a PR on the project.

IN the meantime, if you use an older numpy, it will likely still work.

2.0 is pretty darn new!

NumPy 2.0 release date: June 16 [2024]

-CHB

Any help would be greatly appreciated.

Thanks,

Jim

Thanks Chris! Numpy 1.26.4 works. I'll post a PR.
