Validate all examples on NPU

Set the target NPU device with PTODSL_TEST_DEVICE_ID (for example 3). If this environment variable is not set, example/test scripts default to 0 (resolved as npu:0) and print a warning.

JIT (AOT) examples also require PTO_LIB_PATH to point to the pto-isa installation so the compiler can find its headers. By default it resolves to /sources/pto-isa, but you can export it to a different path before running.

export PTODSL_TEST_DEVICE_ID=0
export PTO_LIB_PATH=/sources/pto-isa  # optional: override the default path
python ./validate_all_examples.py

What it does

  • Scans examples/**/README.md (excluding this top-level README).
  • Reads the first fenced code block marked as bash, sh, shell, or unlabeled.
  • Runs each command in that example's directory with subprocess.
  • Continues running remaining examples even if one fails.
  • Prints a pytest-like summary with PASSED/FAILED entries and failure details.
