Hello @670555467 ,

I noticed you have a problem with the grouping function in your code. The error you are experiencing is TypeError: 'type' object is not subscribable. To better understand and diagnose the problem, I would like to ask you for additional information.

Could you please provide the following details:

• 1. Input data: Please share your noisy_image.
• 2. The configuration settings: It would also be helpful to know the specific configuration settings you used in BM3D.

Once I have this information, I can investigate the issue further and help you fix it.

I look forward to your reply.

I'm sorry to reply to you now, but mine is Python=3.8, using regular images directly.
def bm3d_ CEST(
img: np.ndarray,
mask: np.ndarray | None = None,
config: dict | None = None,
multi_ processing: bool = False,
) -> np.ndarray:
img = (img * 255).astype("int16")
if not multi_ processing:
for dyn in range(img.shape[-1]):
img[:, :, dyn] = bm3d(img[:, :, dyn], config, mask)
else:
with pool.Pool(12) as p:
res = p.imap_ unordered(
run_ ml,
[(img[:, :, dyn], mask, config, dyn) for dyn in range(img.shape[-1])],
)
for d_ img, dyn in res:
img[:, :, dyn] = d_ img
return img / 255.0
At this location, an error will be prompted directly

@670555467 Thanks for your feedback, since I added Type Annotations afterward in the code, Python 3.10 or a higher version is required. Unfortunately, in the current ReadMe there is still wrong information regarding this, but I will correct it immediately. If you use python 3.10 everything should work.

So you can test the functionality:

pip install -r requirements.txt
pip install pytest
cd BM3D
pytest
