我正试图通过两个步骤将Keras模型（LSTM）转换为TFlite，以便在Android上进行部署。
我已经调整了代码，并将其与我的模型结合起来：
from sklearn.utils import class_weight
from sklearn.model_selection import train_test_split
from keras.models import Sequential
from keras.layers import Dense
from keras.layers import LSTM
from keras.layers import Dropout
from keras.layers import Flatten
from keras.utils import to_categorical
from keras.optimizers import Adam
from keras import backend as K
from tensorflow.python.framework.graph_util import convert_variables_to_constants
import tensorflow as tf
from tensorflow.python.tools import freeze_graph
from tensorflow.python.tools import optimize_for_inference_lib
import os
import os.path as path
MODEL_NAME = 'pronation_classifier'
def evaluate_model(X_train, labels_train_cat, X_test, labels_test_cat):
verbose, epochs, batch_size = 1, 50, 64
n_timesteps, n_features, n_outputs = X_train.shape[1], X_train.shape[2], labels_train_cat.shape[1]
model = Sequential()
model.add(LSTM(100, return_sequences=True, input_shape=(n_timesteps,n_features)))
model.add(LSTM(100, return_sequences=True))
model.add(LSTM(100))
model.add(Dropout(0.5))
model.add(Dense(100, activation='relu'))
model.add(Dense(n_outputs, activation='softmax'))
model.compile(Adam(lr=1e-2), loss='categorical_crossentropy', metrics=['accuracy', ])
model.fit(X_train, labels_train_cat, epochs=epochs, batch_size=batch_size, verbose=verbose, class_weight=class_weights)
return model
def export_model(saver, model, input_node_names, output_node_name):
tf.train.write_graph(K.get_session().graph_def, 'out', \
MODEL_NAME + '_graph.pbtxt')
saver.save(K.get_session(), 'out/' + MODEL_NAME + '.chkp')
freeze_graph.freeze_graph('out/' + MODEL_NAME + '_graph.pbtxt', None, \
False, 'out/' + MODEL_NAME + '.chkp', output_node_name, \
"save/restore_all", "save/Const:0", \
'out/frozen_' + MODEL_NAME + '.pb', True, "")
input_graph_def = tf.GraphDef()
with tf.gfile.Open('out/frozen_' + MODEL_NAME + '.pb', "rb") as f:
input_graph_def.ParseFromString(f.read())
output_graph_def = optimize_for_inference_lib.optimize_for_inference(
input_graph_def, input_node_names, [output_node_name],
tf.float32.as_datatype_enum)
with tf.gfile.FastGFile('out/opt_' + MODEL_NAME + '.pb', "wb") as f:
f.write(output_graph_def.SerializeToString())
print("graph saved!")
X_train, X_test, labels_train, labels_test = train_test_split(steps_stack, steps_labels, test_size = 0.2)
labels_train_cat = to_categorical(labels_train)
labels_test_cat = to_categorical(labels_test)
class_weights = class_weight.compute_class_weight('balanced', np.unique(labels_train), labels_train)
model, summary = evaluate_model(X_train, labels_train_cat, X_test, labels_test_cat)
input_node = [node.op.name for node in model.inputs]
output_node = [node.op.name for node in model.outputs]
session = K.get_session()
min_graph = convert_variables_to_constants(session, session.graph_def, [node.op.name for node in model.outputs])
tf.train.write_graph(min_graph, "~/out/", "file.pb", as_text=True)
export_model(tf.train.Saver(), model, [input_node], output_node)
以上所有作品（或似乎）。
错误： 使用 GraphDef 中的 tfile_converter ：

其要点是重复“转换不支持的操作”和“缺少操作节点”，但我不知道如何解决。
使用 saved_model 中的 tflite_convert ：
tflite_convert --output_file=convModel.tflite --saved_model_dir /Users/mila/Bioengineering_Year_4/MHML/pronation_classification/checkpoint
The code above leaves me with:
/Users/mila/anaconda3/lib/python3.6/site-packages/h5py/__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.

再次，我已经调查了此错误，但无法修复。
我尝试了其他将keras转换为.pb的方法，以查看是否可能是导致错误的原因，但它们在步骤2中也失败了。我还尝试了将其从会话的GraphDef以及tfile_converter进行转换。使用python（而不是控制台）-长话短说，这也不起作用。
我知道this和this帖子（以及许多其他令人遗憾的未答复帖子），但它们与我的错误有所不同。
谢谢！非常感谢您的帮助！
