Nano Known Issues#
AttributeError: module ‘distutils’ has no attribute ‘version’#
This usually is because the latest setuptools does not compatible with PyTorch 1.9.
You can downgrade setuptools to 58.0.4 to solve this problem.
For example, if your
setuptools is installed by conda, you can run:
conda install setuptools==58.0.4
Bus error (core dumped) in multi-instance training with spawn distributed backend#
This usually is because you did not set enough shared memory size in your docker container.
You can increase
--shm-size to a larger value, e.g. a few GB, to your
docker run command, or use
If you are running in k8s, you can mount larger storage in
/dev/shm. For example, you can add the following
volumeMount in your pod and container definition.
spec: containers: ... volumeMounts: - mountPath: /dev/shm name: cache-volume volumes: - emptyDir: medium: Memory sizeLimit: 8Gi name: cache-volume
Model.xxx in graph mode is not supported when the
Model instance was constructed with eager mode enabled.#
Nano keras only supports running in eager mode, if you are using graph mode, please make sure not to import anything from
Nano keras multi-instance training currently does not suport tensorflow dataset.from_generators, numpy_function, py_function#
Nano keras multi-instance training will serialize TensorFlow dataset object into a
graph.pb file, which does not work with
dataset.py_function due to limitations in TensorFlow.
RuntimeError: A keras.Model for quantization must include Input layers.#
You may meet this error when running quantization, INC quantization doesn’t support model without
Input layer, you can use OpenVINO or ONNXRuntime in this case, i.e.
InferenceOptimizer.quantize(model, accelerator="openvino", ...) or
InferenceOptimizer.quantize(model, accelerator="onnxruntime", ...)
RuntimeError: Inter op parallelism cannot be modified after initialization#
If you meet this error when import
bigdl.nano.tf, it could be that you have already run some TensorFlow code that set the inter/intra op parallelism, such as
tfds.load. You can try to workaround this issue by trying to import
bigdl.nano.tf first before running TensorFlow code. See https://github.com/tensorflow/tensorflow/issues/57812 for more information.
protobuf version error#
pip install ray[default]==1.11.0 will install
google-api-core>=2.10.0, which depends on
protobuf>=3.20.1. However, nano depends on
protobuf==3.19.4, so you will meet this error if you install
bigdl-nano. The solution is
pip install google-api-core==2.8.2 before installing
