The Ubuntu installer writes environment variables into the profile files shared by all users, so that CUDA_HOME, CUDA_PATH, CUDNN_PATH and the CUDA tool paths take effect for all users; libraries are registered at the system level, so no LD_LIBRARY_PATH is needed; the use-cuda 12.9 command can temporarily switch a single terminal to CUDA 12.9; old configuration lines in the user's ~/.bashrc that switch CUDA versions are backed up and then removed.

UnverifiedPyTorch embeds a specific version of the CUDA runtime library into its installation package, so there is no need to separately install the full CUDA SDK at the beginner stage.72% similarUnverifiedThe core of CUDA includes the CUDA runtime and driver layer, the PTX intermediate instruction set, and companion libraries such as cuDNN, cuBLAS, and TensorRT.66% similarUnverifiedThe root cause of this bug is that the official image was built on CUDA 12.9, but when installing the low-level libraries related to audio processing it mistakenly pulled in CUDA 13 components.64% similarUnverifiedMany third-party libraries and models embed CUDA code using methods such as torch.utils.cpp_extension, and these paths often require dedicated alternatives on non-CUDA backends.64% similarUnverifiedThere is binary incompatibility between major versions of NVIDIA's CUDA toolkit, and pre-compiled packages for PyTorch/JAX are bound to specific CUDA versions63% similar
