问题
我从此page下载了FaceNet的Tensorflow模型,并尝试将其从.pb转换为.onnx文件,但是会引发以下错误:

其他上下文
我没有运行任何CUDA或类似产品,仅运行CPU。 下载的模型为20180402-114759。 这是我第一次使用此工具,而且我在这个AI世界中还是一个初学者,所以我可能会错过一些显而易见的东西。 当然,我多次检查了路径和命令语法。 可能与我下载的文件格式有关吗?

是否可能缺少一些要安装的库? 似乎与某些CUDA实现有关,我没有。 有可能吗?
答案 0 :(得分:1)
您正在使用的命令:
python -m tf2onnx.convert --saved-model home/xesk/Desktop/2s/20180402-114759/20180402-114759.pb --output model.onnx
请注意,您使用的Facenet训练模型只有冻结图(.pb
文件)和检查点(.ckpt
),没有 {{1} } 您的命令正在寻找。
因此,基本上,您是将路径传递到冻结图的saved-model
文件,该路径与 SavedModel 的.pb
文件不同(您不必有)。保存的模型将具有 .pb
文件夹以及variables
文件。
这就是错误的原因:
saved_model.pb
详细了解SavedModel here。
要继续进行ONNX转换,您有两个选择:
为此使用以下code:
OSError: SavedModel file does not exist
注意:import os
import tensorflow as tf
trained_checkpoint_prefix = 'model-20180402-114759.ckpt-275'
export_dir = os.path.join('export_dir', '0')
graph = tf.Graph()
with tf.compat.v1.Session(graph=graph) as sess:
# Restore from checkpoint
loader = tf.compat.v1.train.import_meta_graph(trained_checkpoint_prefix + '.meta')
loader.restore(sess, trained_checkpoint_prefix)
# Export checkpoint to SavedModel
builder = tf.compat.v1.saved_model.builder.SavedModelBuilder(export_dir)
builder.add_meta_graph_and_variables(sess,
[tf.saved_model.TRAINING, tf.saved_model.SERVING],
strip_default_attrs=True)
builder.save()
,.data
和.index
应该具有相同的前缀,然后此代码才能工作。因此,重命名.meta
文件。
.meta
mv model-20180402-114759.meta model-20180402-114759.ckpt-275.meta
文件或ckpt
进行onnx转换从检查点格式:
frozen-graph.pb
从graphdef /冻结图形格式:
python -m tf2onnx.convert --checkpoint tensorflow-model-meta-file-path --output model.onnx --inputs input0:0,input1:0 --outputs output0:0
如果TensorFlow模型采用的格式不是 python -m tf2onnx.convert --graphdef tensorflow-model-graphdef-file --output model.onnx --inputs input0:0,input1:0 --outputs output0:0
,则需要提供 saved model
和 {{ 1}} 。
来自this:
如果模型采用检查点或 graphdef 格式,但您不知道 模型的输入和输出节点,您可以使用 summarize_graph 。 summarize_graph工具可以 需要从源代码下载和构建。如果您可以选择 前往模型提供者并在已保存的模型中获取模型 格式,那么我们建议您这样做。
