Error while running MIL_train.py

[naveenagorre]

Hello, I'm working on running the MIL_train script and it's throwing me the below mentioned error:

• raise exception ctypes.ArgumentError: Caught ArgumentError in DataLoader worker process 0.
• read_region(slide, buf, x, y, level, w, h), ctypes.ArgumentError: argument 3: <class 'TypeError'>: wrong type. I have tried multiple clues available online but none seems to work.

Any suggestions what's going on.

OS - Linux
Openslide-python version 1.1.2

Hi,naveenagorre. I run the code recently and I got the same errors. So could you tell me how you deal with the error? Thanks a lot.

Hi huo, Thank you for reaching out. Few of my input variables obtained from dictionary are not int/float which is what the code expects. I have tried converting them into int/float and now I'm able to fix it. Also there is another repo who have also implemented code for MIL/RNN. https://github.com/TankZhouFirst/clinical-grade-computational-pathology-using-weakly-supervised-deep-learning-on-whole-slide-images Regards [image002] Naveena Gorre Machine Learning Engineer Moffitt Cancer Center 12902 Magnolia Drive, Tampa, FL 33612 | email: ***@***.***> From: qiyueliuhuo23 ***@***.***> Sent: Friday, July 1, 2022 5:49 AM To: MSKCC-Computational-Pathology/MIL-nature-medicine-2019 ***@***.***> Cc: Gorre, Naveena ***@***.***>; Author ***@***.***> Subject: EXT:Re: [MSKCC-Computational-Pathology/MIL-nature-medicine-2019] Error while running MIL_train.py (Issue #20) Hi,naveenagorre.
