Help with error: Cannot locate class or function path: ‘AddChanneld’.

[ebaldelomar]

Hi,

I've been getting an error:

raise ModuleNotFoundError(f"Cannot locate class or function path: ‘{__path}’.")
ModuleNotFoundError: Cannot locate class or function path: ‘AddChanneld’.

I'm trying to get MONAILabel up and running. I got all things installed, downloaded the test data set, and started the server. I’m trying to test out the case 2 example in the Quickstart documentation (Quickstart — MONAI Label 0.8.5 Documentation).

I have searched both the monai/ and monailabel/ folders for 'AddChanneld'

grep --include=*.{py} -rnw '/bmr207/nmrgrp/nmr141/.local/lib/python3.8/site-packages/' -e "AddChanneld"

Output:

/bmr207/nmrgrp/nmr141/.local/lib/python3.8/site-packages/monailabel/tasks/infer/basic_infer.py:171: monai.transforms.AddChanneld(keys='image'),

The only two files that actually use 'AddChanneld' (not commented out) are:

• tests/unit/activelearning/test_epistemic.py:73
• tests/unit/deepedit/test_deepedit_transforms.py

I found this thread (Project-MONAI/tutorials#1686) that talked about this AddChannel issue before but it's not clear to me how one goes about properly editing it; and if it's still the appropriate issue.

When checking version of things using:

python -c "import monai; monai.config.print_config()"

I get the following output if helpful:

MONAI version: 1.3.2
Numpy version: 1.23.4

(A separate question I had was that, even though I just installed this week, I thought the most stable release would be version 1.4? I'm using the 'pip install monai')
