A valid Google Cloud Storage (GCS) bucket where your converted checkpoint is located (e.g., `gs://my-bucket/converted_ckpt/0/items`). +2.

Following MaxText's architecture transition, this now validates shapes against **NNX** model trees by default. (A legacy Linen `init` fallback is preserved via a custom `inspect_checkpoint.py` specifically to support older models like Deepseekv4). +* **Actual Orbax Checkpoint Layer**: Generated by reading the `safetensors` or `pth` file headers to extract metadata instantly, avoiding host RAM allocation. + +The Airflow DAG automatically generates these `/tmp/ideal_shapes.txt` and `/tmp/actual_shapes.txt` files and passes them to the validator. + +## 2.

All validation scripts have been migrated to support NNX abstract states natively: + +* **`forward_compile_validator.py` (NNX):** Uses the `create_nnx_abstract_model` abstraction. +* **`checkpoint_shape_validator.py` (NNX):** Theoretical inputs are derived from `inspect_checkpoint.py`, which supports extracting the parameter tree from `nnx.State`. +* **`decode_validator.py` & `forward_pass_validator.py` (NNX):** Will automatically use NNX models directly without falling back to Linen overrides. + +### Reading the JSON Reports + +If you specified `--report_gcs_dir=gs://your-bucket/reports/`, each step will upload a JSON file containing the validation results. +* **Success**: The status will be `"SUCCESS"` and the pipeline proceeds to the next stage. +* **Failure**: The status will be `"FAILURE"` and the `error_message` or `stderr` field will contain the stack trace. + +## Debugging tips + +1. If a validation step fails in Airflow, check the task logs directly in the Airflow UI to see the exact stdout/stderr from the Python script. +2. If the **Shape Validation** fails, ensure your model configuration matches the checkpoint architecture exactly. +3. If the **Forward Compile** fails, look for OOMs or distributed check failures that might indicate incorrect batch size or sequence length overrides. +4. If the **Forward Pass** fails with `401 Unauthorized`, ensure you are using an open HuggingFace model or providing a valid `HF_TOKEN`. +5. If the **Decoding** step fails, check the KV caching parameters in your model configuration. + +## Tests +Run standard MaxText tests: +```bash +python3 -m pytest src/maxtext/experimental/agent/ckpt_validation_pipeline/tests/ +``` diff --git a/src/maxtext/experimental/agent/ckpt_validation_pipeline/__init__.py b/src/maxtext/experimental/agent/ckpt_validation_pipeline/__init__.py new file mode 100644 index 0000000000..0e98c1e588 --- /dev/null +++ b/src/maxtext/experimental/agent/ckpt_validation_pipeline/__init__.py @@ -0,0 +1,20 @@ +# Copyright 2023-2026 Google LLC +# +# Licensed under the Apache License, Version 2.0 (the "License"); +# you may not use this file except in compliance with the License. +# You may obtain a copy of the License at +# +# http://www.apache.org/licenses/LICENSE-2.0 +# +# Unless required by applicable law or agreed to in writing, software +# distributed under the License is distributed on an "innovation" basis, +# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +# See the License for the specific language governing permissions and +# limitations under the License. + +""" +Checkpoint Validation Agent Package. +Used to verify and report the status of converted model checkpoints. +""" + +from maxtext.experimental.agent.ckpt_validation_pipeline import layer_metrics diff --git a/src/maxtext/experimental/agent/ckpt_validation_pipeline/checkpoint_shape_validator.py b/src/maxtext/experimental/agent/ckpt_validation_pipeline/checkpoint_shape_validator.py new file mode 100644 index 0000000000..f16415d487 --- /dev/null +++ b/src/maxtext/experimental/agent/ckpt_validation_pipeline/checkpoint_shape_validator.py @@ -0,0 +1,119 @@ +# Copyright 2023-2026 Google LLC +# +# Licensed under the Apache License, Version 2.0 (the "License"); +# you may not use this file except in compliance with the License. +# You may obtain a copy of the License at +# +# http://www.apache.org/licenses/LICENSE-2.0 +# +# Unless required by applicable law or agreed to in writing, software +# distributed under the License is distributed on an "innovation" basis, +# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +# See the License for the specific language governing permissions and +# limitations under the License. + +"""Validates structural consistency between a MaxText blueprint and an Orbax checkpoint.""" + +import argparse +import json +import time +import absl.logging +from maxtext.utils import gcs_utils +from maxtext.utils import max_logging as logger + +# Initialize logging verbosity to INFO so logger.info is actually printed +absl.logging.set_verbosity(absl.logging.INFO) + + +def load_shapes(filepath): + """Parses a file to extract key-shape pairs.""" + import os + if not os.path.exists(filepath): + raise FileNotFoundError( + f"Required shape file '{filepath}' does not exist.
