现在不是都用keras生成h5格式文件，然后用tflite_convert 吗？

问题来源

写了个很简单的RNN LSTM 模型

input = keras.Input(shape=(X_train.shape[1], X_train.shape[2]))
x = layers.LSTM(64, return_sequences = True)(input)
x = layers.LSTM(64)(x)
output = layers.Dense(6, activation='softmax')(x)
model = keras.Model(inputs=input, outputs=output)
model.summary()
Model: "model"
_________________________________________________________________

input_2 (InputLayer) [(None, 200, 3)] 0

_________________________________________________________________
lstm_2 (LSTM) (None, 64) 33024

LSTM并不是所有的类型都支持，该模型的底层实现使用了？

https://www.tensorflow.org/lite/convert/rnn

怎样看keras的实现使用的是什么operator？

使用Tensorflow构建模型，控制使用的LSTM类型

https://medium.com/@curiousily/human-activity-recognition-using-lstms-on-android-tensorflow-for-hackers-part-vi-492da5adef64

# Stack 2 LSTM layers

lstm_layers = [tf.contrib.rnn.BasicLSTMCell(N_HIDDEN_UNITS, forget_bias=1.0)
for _ in range(2)]
lstm_layers = tf.contrib.rnn.MultiRNNCell(lstm_layers)
outputs, _ = tf.contrib.rnn.static_rnn(lstm_layers, hidden, dtype=tf.float32)
# Get output for the last time step lstm_last_output = outputs[-1]

怎样把得到的pb文件转化成tflite

https://zhuanlan.zhihu.com/p/59496851

这篇提到使用bazel build生成源码相关的工具，感觉比较靠谱，关键是bazel 还算熟悉

查看模型结构的工具：得到toco的输入参数
$ bazel build tensorflow/tools/graph_transforms:summarize_graph

格式转化的工具

$ bazel build tensorflow/lite/toco:toco

bin文件编出后，可以copy到需要的路径下，如pb文件所在的路径

./summarize_graph --in_graph=frozen_har.pb
Found 1 possible inputs: (name=input, type=float(1), shape=[?,200,3])
No variables spotted.
Found 1 possible outputs: (name=y_, op=Softmax)
Found 67919 (67.92k) const parameters, 0 (0) variable parameters, and 0 control_edges
Op types used: 1230 Const, 1200 Mul, 1200 Sigmoid, 802 Add, 800 Tanh, 404 ConcatV2, 402 MatMul, 401 Split, 400 BiasAdd, 8 Identity, 4 ExpandDims, 4 Fill, 1 Transpose, 1 StridedSlice, 1 Softmax, 1 Shape, 1 Reshape, 1 Relu, 1 Placeholder
To use with tensorflow/tools/benchmark:benchmark_model try these arguments:
bazel run tensorflow/tools/benchmark:benchmark_model -- --graph=frozen_har.pb --show_flops --input_layer=input --input_layer_type=float --input_layer_shape=-1,200,3 --output_layer=y_

toco的基本参数意义(主要里面有废弃的参数)

--input_file=""
string
Input file (model of any supported format).
For Protobuf formats, both text and binary are supported regardless of file extension.

--output_file=""
string
Output file. For Protobuf formats, the binary format will be used.

--output_format="TFLITE"
string
Output file format. One of TENSORFLOW_GRAPHDEF, TFLITE, GRAPHVIZ_DOT.

--inference_type=""
string
Target data type of arrays in the output file (for input_arrays, this may be overridden by inference_input_type).
One of FLOAT, QUANTIZED_UINT8.

--inference_input_type=""
string
Target data type of input arrays. If not specified, inference_type is used. One of FLOAT, QUANTIZED_UINT8.

--input_arrays=""
string
Names of the input arrays, comma-separated. If not specified, will try to read that information from the input file.

--output_arrays=""
string Names of the output arrays, comma-separated. If not specified,
will try to read that information from the input file.

--input_shapes=""
string
Shapes corresponding to --input_arrays, colon-separated. For many models each shape takes the form batch size, input array height, input array width, input array depth.

--input_data_types=""
string
Input arrays types, comma-separated, if not already provided in the graph.
Typically needs to be specified when passing arbitrary arrays to --input_arrays.

input_shapes=[?,200,3]

这里写？、-1还是1， 从错误信息看出应该写1

生成的tflite文件比pb文件还大这正常吗？

-rw-r--r-- 1 ws ws 1393628 7月 5 16:56 frozen_har.pb
-rw-rw-r-- 1 ws ws 1399504 7月 5 17:37 frozen_har.tflite

模型文件的不同格式

GraphDef(.pb),

FrozenGraphDef (.pb with frozen variables),

SavedModel (.pb – used to infer the common format on the server side), and

Checkpoint files (serialized variables during training).

SavedModel

Training Model will generate 3 files representing the network structure. We care about GraphDef and checkpoint files.

-rw-r--r-- 1 ws ws 73 6月 28 16:52 checkpoint
-rw-r--r-- 1 ws ws 800336 6月 28 16:52 har.ckpt.data-00000-of-00001
-rw-r--r-- 1 ws ws 955 6月 28 16:52 har.ckpt.index

-rw-r--r-- 1 ws ws 16349895 6月 28 16:52 har.pbtxt
此时使用Tensorboard 看到图是training的图

Since we named the input and output layers, we can easily identify them and then begin to understand which layers are necessary for inference and which layers can be discarded.

Again, everything before the input_tensor is not necessary. We need to crop this image before executing it on the mobile device. Most training layers in TFLite are also not supported.

Freeze graph

– this will freeze checkpoint variables in GraphDef

freeze_graph

--input_graph=/tmp/mnist_graph_def_with_ckpts/graph.pbtxt

--input_checkpoint=/tmp/mnist_graph_def_with_ckpts/model.ckpt-48000

-input_binary=false

--output_graph=/tmp/mnist_graph_def_with_ckpts/frozen_mnist.pb

--output_node_names=softmax_tensor

If you installed TensorFlow with pip, you will get the freeze_graph command. ( installation instructions )
Open the checkpoint file and determine the latest file. In our case it is model.ckpt-48000
The Input binary option is false because we are passing a .pbtxt file instead of .pb (in which case it should be true).
The hardest part is identifying the output_node_name, but since we gave it a name in the training script, it's easy. If you don't provide a training script for the model you're building, you'll need to use Tensorboard and find the automatically generated name for it (I spent a lot of time trying to understand this, so in short, the training script is handy is a huge one.) reward). tf.nn.softmax(logits, name='softmax_tensor'),

Note that freeze_graph actually removes most of the layers used in the training. However, we still have something that is incompatible with TFLite. Specifically, notice the "dropout" and "iterator" layers. These layers are used for training and still need to be cropped (optimize_for_inference当前已经没有这个工具？)

TFLite

The final step is to execute the toco tool and the TensorFlow Lite optimized converter.

也就是上面说的toco工具

TFLite post_training_quantize

/toco --input_file='30_cnn.tflite' --input_format=TFLITE --output_format=TFLITE --output_file='quanized_30_cnn.tflite' --inference_type=FLOAT --input_type=FLOAT --input_arrays=conv1d_input --output_arrays=Identity --input_shapes=1,80,3 --post_training_quantize

Quantization(但依赖saved model dir)

使用底层tensorflow API才能得到SavedModel? keras可以吗？

By reducing the precision of values and operations within a model, quantization can reduce both the size of model and the time required for inference. For many models, there is only a minimal loss of accuracy.

The TensorFlow Lite converter makes it easy to quantize TensorFlow models. The following Python code quantizes a SavedModel and saves it to disk:

import tensorflow as tfconverter = tf.lite.TFLiteConverter.from_saved_model(saved_model_dir)
converter.optimizations = [tf.lite.Optimize.OPTIMIZE_FOR_SIZE]
tflite_quant_model = converter.convert()
open("converted_model.tflite", "wb").write(tflite_quantized_model)

使用TOCO工具 --post_training_quantize用于模型压缩

注意要使用源码编译出参考上面的bazel build 自动安装的toco不行

网上给的例子都是pb到tflite 且quantization, 但没有tflite作为输入进行quantization的例子

bazel-bin/tensorflow/lite/toco/toco --input_file='../kerasyolo3/m/transfer_multi_4cl_1207.pb' --input_format=TENSORFLOW_GRAPHDEF --output_format=TFLITE --output_file='../kerasyolo3/m/transfer_multi_4cl_1207.tflite' --inference_type=FLOAT --input_type=FLOAT --input_arrays=input_1 --output_arrays=output_1,output_2,output_3 --input_shapes=1,416,416,3

仔细看toco的help: 这里的输入格式可以是TFLITE

--input_format="TENSORFLOW_GRAPHDEF" string Input file format. One of: TENSORFLOW_GRAPHDEF, TFLITE.

./toco

--input_file='30_cnn.tflite'

--input_format=TFLITE

--output_format=TFLITE

--output_file='quanized_30_cnn.tflite'

--inference_type=FLOAT

--input_type=FLOAT

--input_arrays=conv1d_input

--output_arrays=Identity

--input_shapes=1,80,3

--post_training_quantize

这里关键的是上面几个参数可以从tflite::PrintInterpreterState(interpreter.get());打印的log看出

Inputs: 1
Outputs: 0

Tensor 0 Identity kTfLiteFloat32 kTfLiteArenaRw 24 bytes ( 0.0 MB) 1 6
