我试图冻结使用 LinearClassifier 训练的图表。该代码几乎与 TensorFlow 中的wide_deep教程相匹配。培训成功完成，估算工作非常顺利（100％成功）。不幸的是，当我试图冻结图表以便将其移植到移动设备上时，我收到错误：
TypeError: names_to_saveables must be a dict mapping string names to Tensors/Variables. Not a variable: Tensor("linear/linear_model/0/weights:0", shape=(1, 14), dtype=float32)
命令是：
python freeze_graph.py --input_graph=/media/LinuxApps/Documents/FFTTestData/fft_piano_model/graph.pbtxt --input_checkpoint=/media/LinuxApps/Documents/FFTTestData/fft_piano_model/model.ckpt-190 output_graph=/media/LinuxApps/Documents/FFTTestData/fft_piano_model/frozen_graph.pb --output_node_names=softmax
Stacktrace是：

有人可以帮忙吗？
谢谢！
