Error caused by calling CRF block

[sduqcj]

（1）I introduced the CRF block at the end of the Unet framework:
def forward(self, x: torch.Tensor) -> torch.Tensor:

    x1 = self.model(x)       

    return CRF()(x,x1)

（2）I want to introduce CRF bloack at the end of the model for post-processing, but the following error is displayed:
monai.utils.module.OptionalImportError: import monai._C (No module named 'monai._C').

（3）After debugging, it is found that CRF module calls the filter function written in C language
import torch

from monai.utils.module import optional_import

_C, _ = optional_import("monai._C")

all = ["BilateralFilter", "PHLFilter"]

There is a problem here. I don't know how to deal with it.

please try the docker image which has a precompiled monai._C in it and the CRF is probably ready-to-use if you can get the docker container running https://docs.monai.io/en/latest/installation.html#from-dockerhub

otherwise you can install it from the source:

BUILD_MONAI=1 pip install --no-build-isolation git+https://github.com/Project-MONAI/MONAI#egg=monai
