【问题描述】:
我将训练我的模型量化意识。但是,当我使用它时,tensorflow_model_optimization 无法量化 tf.reshape 函数,并引发错误。
- 张量流版本:'2.4.0-dev20200903'
- python 版本:3.6.9
代码:
import os
os.environ['CUDA_VISIBLE_DEVICES'] = '3'
from tensorflow.keras.applications import VGG16
import tensorflow_model_optimization as tfmot
import tensorflow as tf
from tensorflow import keras
from tensorflow.keras import layers
quantize_model = tfmot.quantization.keras.quantize_model
inputs = keras.Input(shape=(784,))
# img_inputs = keras.Input(shape=(32, 32, 3))
dense = layers.Dense(64, activation="relu")
x = dense(inputs)
x = layers.Dense(64, activation="relu")(x)
outputs = layers.Dense(10)(x)
outputs = tf.reshape(outputs, [-1, 2, 5])
model = keras.Model(inputs=inputs, outputs=outputs, name="mnist_model")
# keras.utils.plot_model(model, "my_first_model.png")
q_aware_model = quantize_model(model)
和输出:
Traceback (most recent call last):
File "<ipython-input-39-af601b78c010>", line 14, in <module>
q_aware_model = quantize_model(model)
File "/home/essys/.local/lib/python3.6/site-packages/tensorflow_model_optimization/python/core/quantization/keras/quantize.py", line 137, in quantize_model
annotated_model = quantize_annotate_model(to_quantize)
File "/home/essys/.local/lib/python3.6/site-packages/tensorflow_model_optimization/python/core/quantization/keras/quantize.py", line 210, in quantize_annotate_model
to_annotate, input_tensors=None, clone_function=_add_quant_wrapper)
...
File "/home/essys/anaconda3/envs/tf_gpu/lib/python3.6/site-packages/tensorflow/python/autograph/impl/api.py", line 667, in wrapper
raise e.ag_error_metadata.to_exception(e)
TypeError: in user code:
TypeError: tf__call() got an unexpected keyword argument 'shape'
如果有人知道,请帮忙?
【问题讨论】:
-
通过使用您的代码,我得到了不同的 Traceback :
RuntimeError: Layer tf_op_layer_Reshape:<class 'tensorflow.python.keras.engine.base_layer.TensorFlowOpLayer'> is not supported. You can quantize this layer by passing a `tfmot.quantization.keras.QuantizeConfig` instance to the `quantize_annotate_layer` API. -
在旧版本中不支持 tf.reshape 但在 tf_nightly 版本中支持。
-
那么你可能想在 Github 上打开一个问题。
-
是的,我想我应该这样做。谢谢。
