autoencoder_mednist transformations failure

Thank you. This solves the issue!

Hi, it seems to be working for me. I'm using the master branch of MONAI, which required another bug fix (Project-MONAI/MONAI#1440), but I didn't see any problems regarding the CacheDataset.

Would you be able to paste the error? And also the output of monai.config.print_debug_info()?

Hi, thank you for the fast response! Sorry for the formatting, it looks awful here. I hope it is readable although not optimal.

This the error output:

---

RuntimeError Traceback (most recent call last)
/usr/local/lib/python3.6/dist-packages/monai/transforms/utils.py in apply_transform(transform, data, map_items)
360 return [transform(item) for item in data]
--> 361 return transform(data)
362 except Exception as e:

9 frames
RuntimeError: can not find suitable reader for this file: /tmp/tmpy56jd7rb/MedNIST/Hand/001061.jpeg.

The above exception was the direct cause of the following exception:

RuntimeError Traceback (most recent call last)
/usr/local/lib/python3.6/dist-packages/monai/transforms/utils.py in apply_transform(transform, data, map_items)
361 return transform(data)

--> 363 raise RuntimeError(f"applying transform {transform}") from e

365

RuntimeError: applying transform <monai.transforms.io.dictionary.LoadImaged object at 0x7f614b16d4a8>`

I'm running it on colab. Here is the debug info:

Hi, you're absolutely right. I think the problem relates to some changes caused by updates to how we read our images.

In colab, I modified the first line to be: %pip install -q "monai-weekly[pillow, tqdm]", and using the weekly release of MONAI solved that problem. You may need to restart the runtime after the pip install.
