Tidak Dapat Mengonversi Model EfficientNetB0 Kustom ke Format Representasi Menengah (IR)

• Model dihasilkan dengan menggunakan kode ini:

  model=tf.keras.applications.EfficientNetB0(

      include_top=True,

      weights=None,

      pooling=max,

      classes=2,

      classifier_activation="softmax"

  )

• Mengonversi model ke format SavedModel
• Menjalankan perintah Pengoptimal Model:

  mo --saved_model_dir model

• Galat yang diterima:

  [ ERROR ]  Cannot infer shapes or values for node "StatefulPartitionedCall".

  [ ERROR ]  Error converting shape to a TensorShape: Failed to convert 'masked_array(data=[--, 224, 224, 3],

               mask=[ True, False, False, False],

         fill_value=-1000000007)' to a shape: 'masked'could not be converted to a dimension. A shape should either be single dimension (e.g. 10), or an iterable of dimensions (e.g. [1, 10, None])..

  [ ERROR ] 

  [ ERROR ]  It can happen due to bug in custom shape infer function .

  [ ERROR ]  Or because the node inputs have incorrect values/shapes.

  [ ERROR ]  Or because input shapes are incorrect (embedded to the model or passed via --input_shape).

  [ ERROR ]  Run Model Optimizer with --log_level=DEBUG for more information.

  [ ERROR ]  Exception occurred during running replacer "REPLACEMENT_ID" (): Stopped shape/value propagation at "StatefulPartitionedCall" node.

Galat yang dihadapi disebabkan oleh beberapa lapisan dalam model kustom yang tidak kompatibel dengan arsitektur Model Optimizer.

Model Intel® Public Pre-Trained EfficientNet yang divalidasi dari Open Model Zoo adalah sebagai berikut:

• efficientnet-b0
• efficientnet-v2-b0
• efficientnet-v2-s
