AssertionError: CPU does not support activation and bias in spconv

[JoaquinAils]

Description:
When attempting to use SubMConv3d with the spconv library (version 2.3.6) on Linux for CPU-only execution, I encountered the following error:

AssertionError: cpu don't support act and bias

Line of Code:
An example of the code triggering the error:

self.logits = SubMConv3d(4 * init_size, nclasses, indice_key="logit", kernel_size=3, stride=1, padding=1, bias=True)

I need the bias to be True
