The function signature/docstring allows None; without this guard, the expert state dict would be incorrectly filtered out.

@AlexMa616 What do you mean incorrectly filtered out? If you don't do the modification, when num_experts is None the function still returns 0. This modification doesn't change the behavior?

You're right,updated.

This is a compatibility fallback for when the NVML API is unavailable in the CUDA environment.

I think we should expose the exception if the NVML API is really unavailable

Description
Expand Metax core unit test coverage for Megatron by adding broad, targeted coverage across core training, checkpointing, inference, tensor-parallel, pipeline-parallel, optimizer, FSDP, and utility paths. The added tests focus on CPU/Metax-compatible execution paths and mock CUDA-only behavior where needed, improving core coverage without changing source logic.
The changes also stabilize the current Metax CI unit test workflow by isolating global test state, avoiding CUDA-only assumptions in coverage tests, and keeping the unit test matrix aligned with the expected shared CI structure.
Type of change
Changes
Metax core coverage expansion: Added high-yield unit coverage for Megatron core paths, including dynamic inference, training helpers, checkpointing, tensor parallelism, pipeline communication, distributed optimizer, FSDP buffers, and core utility surfaces.
Metax-compatible test stabilization: Adjusted tests to avoid CUDA-only assumptions where possible, isolate global test state, and make mocked distributed/CUDA behavior deterministic in the current Metax CI image.
Dynamic inference coverage: Added coverage for dynamic text generation server endpoints, request lifecycle paths, dynamic context/cache handling, graph setup/reset paths, and KV block allocator behavior.
Training and checkpointing coverage: Added coverage for training state helpers, gradient finalization/scheduler paths, checkpoint metadata/version handling, distributed checkpointing utilities, timers, and exchange helpers.
Parallelism and optimizer coverage: Added coverage for tensor-parallel RNG/mapping helpers, pipeline communicator/schedule paths, distributed optimizer static helpers, FSDP buffer/grouping paths, and related CPU-safe surfaces.
