F.set_kmap_mode() has no effect

Is there an existing issue for this?

Current Behavior

I am using the bleeding-edge TorchSparse library and it seems like F.set_kmap_mode("hashmap") has no effect. My code looks as follows:

from torchsparse.nn import functional as F

F.set_kmap_mode("hashmap")

However, it appears that my convolution ops are still using the "hashmap_on_the_fly" kmap mode. I get an error message saying ValueError: Unsupported kmap_mode: hashmap_on_the_fly for generative convolution (please switch to kmap_mode=hashmap).

The following code snippet does seem to work, but it is slightly more involved (and not clear from the docs):

conv_config = F.conv_config.get_default_conv_config(conv_mode=F.get_conv_mode())
conv_config.kmap_mode = 'hashmap'
F.conv_config.set_global_conv_config(conv_config)

Expected Behavior

I expect that F.set_kmap_mode("hashmap") would change the kmap mode used for convolution.
