Describe the bug
I follow the instructions from the official website, installing nerfstudio and tinycudann.
And I can also run "nerfacto" well, but when I want to change to model "lerf", the problem occurs: "NameError: name 'tcnn' is not defined.".

To Reproduce
Steps to reproduce the behavior:

1. Build a virtual environment using conda, and install nerfstudio and tinycudann. All the installation setups are followed as the official materials say.
2. using "ns-train lerf" to install lerf model.
3. using "ns-train lerf --data ./output" to train the model
4. See error

Expected behavior
I expected it run smoothly, without error
