The TensorFlow model is used to store/load the tensorflow model.

Each time you call the estimator train, eval, or Predict method, the following occurs: Estimator builds the model diagram by running MODEL_FN (). (For more information on MODEL_FN (), see Creating a Custom Estimator.) Estimator initializes the weights of the new model based on the data stored in the most re
We often need to save the PB file of the TensorFlow model, which is very handy when using the Tf.graph_util.convert_variables_to_constants function. 1. Training Network: fully_conected.py

Generate the checkpoint file (chekpoint file). The extension is. ckpt, And the tf. train. Saver object is generated by calling Saver. save. Contains weights and other program-Defined variables, excluding the graph structure. Another program needs to re-create the graphic structure to t
appropriate algorithm to get the expected exact value.
Model evaluation: Evaluate the accuracy of the model according to the test set.
Model application: Deploy the model and apply it to the actual production environment.
Application Effectiveness Assessment:
The TensorFlow training model is usually written using the Python API and simply records how the models are invoked in Java after they are saved.
In Python, the model is saved using the following API:
# Save binary model
Output_graph_def = tf.graph_util.convert_variables_to_constants (Sess, Sess.graph_def, Output_node
In the previous article, "TensorFlow load pre-training model and save Model", we learned how to use the pre-training model. Note, however, that in the previous article, you must have at least 4 files to use the pre-training model:

M1, m2, m3, and m4 indicate the scale and rotation characteristics. tx indicates the translation in the x direction and ty indicates the translation in the y direction.
Then the coordinates of a matching point can be written

Where (x, y) is before transformation, (u, v) is the coordinate after transformation.
To understand how to evaluate the affine transformation parameters, perform the foll
Summarize some of the experiences of learning to use tensorflow during this time. The main scenario is to use the Python language to train a simple LR model and save the model in Savedmodel format, then restore the model in Python and the Java language to predict the results.

We can find the answer by defining the two terms:* gain = (expected response of the application Prediction model)/(expected response sent randomly) *elevation = (expected response of the first 10,000 users applying the forecast model)/(expected response of

This article mainly introduces the TensorFlow introduction to use Tf.train.Saver () to save the model, now share to everyone, but also to make a reference. Come and see it together.

When defining saver, you typically define the maximum number of saved models, in general, if
