Issue: Failed to load libtilert.so due to undefined symbol _ZN3c104cuda29c10_cuda_check_implementationEiPKcS2_ib

Description

When running the generate script in a Docker environment, I encounter an error loading the libtilert.so library due to an undefined symbol related to PyTorch's CUDA checks.

Error Log

(tilert) [root@d9878fa39ee8 workspace]# python generate.py     --model-weights-dir "/home/model_weights" 2>&1 | tee generate.log

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/workspace/generate.py", line 9, in <module>
    from tilert import logger, tilert_init
  File "/opt/conda/envs/tilert/lib/python3.12/site-packages/tilert/__init__.py", line 43, in <module>

    raise RuntimeError(f"Failed to load library from {lib_path}") from e
RuntimeError: Failed to load library from /opt/conda/envs/tilert/lib/python3.12/site-packages/tilert/libtilert.so

Environment

• Running in Docker container

Reproduce the failure with generate.py in the Docker environment, then inspect tilert/init.py where libtilert.so is loaded and compare the installed PyTorch/CUDA environment with the library's requirements. Done means generate.py loads libtilert.so without the undefined-symbol error and proceeds past the import.
