Validate substitution keys before accepting the plugin.
_validate accepts noncanonical SUBSTITUTIONS keys. _substitute canonicalizes requirement names before direct lookup, so a key such as cucim_cu12 does not replace cucim-cu12. Reject noncanonical keys or normalize the mapping, and add a test for this case.

MONAI's dependency lists name the packages published for NVIDIA hardware (cucim-cu*, cupy-cuda*, nvidia-*). None of them install or import on AMD ROCm, so monai[all] and monai[cucim] are unusable there, and Dockerfile.rocm had to grep them back out of the requirements it generated. Rather than add a ROCm-specific escape hatch, introduce a general accelerator-vendor mechanism: when MONAI is built or installed against a given vendor's PyTorch, that vendor's plugin rewrites the dependency lists. The extras keep their upstream names and meanings, and pyproject.toml stays the single, statically readable source of truth. monai/config/vendor_deps.py holds the generic engine -- requirement parsing, substitution, de-duplication, the vendor registry and active_vendor(). It carries no vendor knowledge beyond a one-line detection probe per registry entry. monai/config/vendor_rocm.py is the first plugin, supplying the AMD substitution table, the device extras and the rocm requirement. Supporting another vendor means adding a registry entry and a vendor_<name>.py; setup.py does not change. MONAI_VENDOR forces a vendor by name or disables rewriting with `none`. On a ROCm torch, cucim-cu12/cucim-cu13 become amd-hipcim, cupy-cuda* becomes amd-cupy, and nvidia-ml-py, nni and nvidia-nvimgcodec-cu* are dropped. amd-hipcim ships the cucim namespace and amd-cupy ships cupy, so every optional_import call site works unchanged -- no runtime code changes. Isolation is the point of the design, and is enforced rather than assumed: - setup.py passes distclass only when a vendor is active, so an NVIDIA or CPU build calls setup() exactly as upstream does. - A plugin module is imported only after its registry probe matches, so a build for one vendor never executes another vendor's code. - monai/__init__.py eagerly imports every submodule, which pulled the packaging modules -- and with them a vendor plugin -- into every `import monai` on every machine. They are now excluded. This predates the vendor work. - A vendor that is detected but whose plugin cannot be loaded, or whose contract is malformed, fails the build. Falling back to the unmodified lists would ship NVIDIA packages in a ROCm wheel, which is worse than failing. The contract is checked on load because neither mistake raises where it would be used: `key in substitutions` is a substring test on a string, so a SUBSTITUTIONS that is not a mapping quietly matches nothing, and lookups are canonicalised, so a key that is not already a PEP 503 name can never match either. - pip build isolation resolves torch afresh, and a plain PyPI wheel outranks a vendor build of the same release under PEP 440, so a source install on an AMD machine can be handed a CUDA torch, detect no vendor, and emit CUDA dependencies at exit 0. MONAI now warns when it finds an AMD GPU but no ROCm torch; MONAI_VENDOR=none keeps a deliberate CPU build on that hardware quiet. The rocm requirement pins the ROCm *release*, never the HIP version. These are different numbers: ROCm 10.0 ships HIP 7.15 and ROCm 10.1 ships HIP 7.16, while the rocm package is versioned by the release, so torch.version.hip or hipcc --version yield a requirement no index can satisfy. Detection reads the release from the tree ROCM_PATH/ROCM_HOME point at, then the rocm package installed here, then `rocm-sdk version`, and only then a system install, so an unrelated /opt/rocm cannot shadow the SDK being built against. Reading files rather than probing PATH also keeps detection working under pip build isolation. The requirement requests the libraries, devel and per-arch device features and spans ROCM_SERIES_SPAN minor series. devel is needed after install, not only to build: rocm-sdk-core ships libamdhip64.so.7 but not the unversioned libamdhip64.so, so only the devel tree can satisfy a link, and monai/_extensions JIT-compiles its HIP sources through torch.utils.cpp_extension.load() on first use. The span reflects measurement: amd-cupy, amd-hipcim and a MONAI wheel built for ROCm 10.0 all run on a 10.1 runtime, and a one-minor ceiling made pip backtrack off the real wheel onto a 0.0.2 PyPI placeholder stub -- a silent downgrade rather than an error. Also report the HIP toolkit version in get_gpu_info() on ROCm builds, where torch.version.cuda is None and print_config() showed "CUDA version: None". Only the key name changes; it stays behind the existing Has CUDA guard. Dockerfile.rocm drops the grep filter and the separate amd-hipcim install step, both now redundant, and passes AMD's index to the main install. docs/source/installation.md documents the vendor mechanism and gives the full ROCm recipe, including the two ways to install from source under build isolation. Verified end to end on an AMD Instinct MI355X: a clean environment installing monai[cucim] from this branch resolves amd-hipcim, amd-cupy and a ROCm torch with zero CUDA packages, and cupy, cucim and MONAI transforms, losses and metrics all run on the GPU. Across isolated CPU-only, NVIDIA and ROCm build environments on a host carrying both a system /opt/rocm and /usr/local/cuda, non-vendor builds are unaffected: generated metadata and print_dependencies.py output are identical to dev, no vendor module is imported, and no distclass is passed. Faults injected into the ROCm plugin -- a SyntaxError, raising at import, raising while computing the requirement, and a malformed substitution table -- each fail the ROCm build and leave the CPU and NVIDIA builds byte-identical. Also verified on an NVIDIA H100.
