我已成功地轉換預先訓練.ckpt模型中使用這個腳本.pb(protobuf的)格式:轉換.pb文件來.ckpt(tensorflow)
import os
import tensorflow as tf
# Get the current directory
dir_path = os.path.dirname(os.path.realpath(__file__))
print "Current directory : ", dir_path
save_dir = dir_path + '/Protobufs'
graph = tf.get_default_graph()
# Create a session for running Ops on the Graph.
sess = tf.Session()
print("Restoring the model to the default graph ...")
saver = tf.train.import_meta_graph(dir_path + '/model.ckpt.meta')
saver.restore(sess,tf.train.latest_checkpoint(dir_path))
print("Restoring Done .. ")
print "Saving the model to Protobuf format: ", save_dir
#Save the model to protobuf (pb and pbtxt) file.
tf.train.write_graph(sess.graph_def, save_dir, "Binary_Protobuf.pb", False)
tf.train.write_graph(sess.graph_def, save_dir, "Text_Protobuf.pbtxt", True)
print("Saving Done .. ")
現在,我要的是副verca程序。我如何加載protobuf文件並將其轉換爲.ckpt(檢查點)格式?
我試圖做到這一點與下面的腳本,但它總是失敗:
import tensorflow as tf
import argparse
# Pass the filename as an argument
parser = argparse.ArgumentParser()
parser.add_argument("--frozen_model_filename", default="/path-to-pb-file/Binary_Protobuf.pb", type=str, help="Pb model file to import")
args = parser.parse_args()
# We load the protobuf file from the disk and parse it to retrieve the
# unserialized graph_def
with tf.gfile.GFile(args.frozen_model_filename, "rb") as f:
graph_def = tf.GraphDef()
graph_def.ParseFromString(f.read())
#saver=tf.train.Saver()
with tf.Graph().as_default() as graph:
tf.import_graph_def(
graph_def,
input_map=None,
return_elements=None,
name="prefix",
op_dict=None,
producer_op_list=None
)
sess = tf.Session(graph=graph)
saver=tf.train.Saver()
save_path = saver.save(sess, "path-to-ckpt/model.ckpt")
print("Model saved to chkp format")
我相信,這將是有這些轉換腳本非常有幫助。
P.S:權重已經嵌入到.pb文件中。
謝謝。
該模型從恢復(sess,tf.train.latest_checkpoint(dir_path))加載檢查點(與權重)的位置。 –
好!在第二個腳本中,您沒有加載任何模型,只是導入了圖形。儘管您在第一個腳本中加載模型,但它不會將變量寫入到pb文件中。 –
好吧我在tf.train.write_graph函數中將sess.graph_def更改爲sess.graph,但同樣的運氣。 –
