+# Patch vLLM v0.24.0+ ``get_physical_gpu_ids_for_local_dp_rank`` so that it
+# tolerates a pre-sharded ASCEND_RT_VISIBLE_DEVICES env var (one slice per
+# DP rank), instead of unconditionally applying ``local_dp_rank * world_size``
+# as an offset into it.
+#
+# Background:
+# PR #45026 removed the per-process device isolation that older vLLM
+# versions performed internally. Application-level DP (e.g.
+# ``offline_data_parallel.py``) now has to slice ASCEND_RT_VISIBLE_DEVICES
+# per rank itself, but the upstream helper still expects the env var to
+# contain ALL devices for ALL ranks and tries to read it with the
+# ``local_dp_rank * world_size`` offset. With a sharded env var, that
+# offset is out of range and the helper raises ``IndexError`` (wrapped in
+# the user-facing "Error computing device indices for ..." message).
