BUG: add option to choose host memory

[Jeanneclre]

Hello @allemangD

I did some changes we discussed in the issue #66. To resume them:

1. Changed this https://github.com/DCBIA-OrthoLab/SlicerAutomatedDentalTools/blob/86026595834472b132aca980b5cc0688359993c3/AMASSS_CLI/AMASSS_CLI.py#L976

with this:

DEVICE = torch.device("cuda" if torch.cuda.is_available() else "cpu")
val_outputs = sliding_window_inference(input_img, cropSize, args["nbr_GPU_worker"], net,
                                       overlap=args["precision"], sw_device= DEVICE, device=device_memory)                                                 

2. Added a checkbox on the User Interface of Amass to enable "CPU memory"
3. Error message in the shell asking user to try to enable CPU as a memory host (couldn't do a pop-up window from the CLI)

Output test: On a machine equipped with an Intel Xeon Gold 6226R CPU running at 2.90GHz, with 62GB of memory and an NVIDIA RTX A6000 48GB, a CBCT scan with an approximate resolution of 0.3mm, covering the maxilla, mandible, skin, and cranial base, was segmented in 126.25 seconds.

Thank you!

Cuda fix looks good imho

Generally the changes look good. I don't think the phrasing of the UI is understandable, though, "CPU usage - check to enable" to me reads as it would execute segmentation on the GPU, I think it may confuse users.

I'd change to something like "Use CPU memory" with a tooltip "Use host memory with a performance penalty. Enable if CUDA runs out of memory." so a user could more easily find it after seeing an error about memory usage.

Thank you for the feedback! I've made the changes. Please let me know if you have any other suggestions. :)

Hi @allemangD I added a function to install the required libraries and their version for AMASS. Should we change the PR title?

Thank you
