Variable scopes in Tensorflow

心已入冬 提交于 2019-12-10 22:46:04
问题 I am having problems making effective usage of variable scopes. I want to define some variables for weights, biases and inner state of a simple recurrent network. I call get_saver() once after defining the default graph. I then iterate over a batch of samples using tf.scan . import tensorflow as tf import math import numpy as np INPUTS = 10 HIDDEN_1 = 2 BATCH_SIZE = 3 def batch_vm2(m, x): [input_size, output_size] = m.get_shape().as_list() input_shape = tf.shape(x) batch_rank = input_shape

Keras callbacks keep skip saving checkpoints, claiming val_acc is missing

I'll run some larger models and want to try intermediate results. Therefore, I try to use checkpoints to save the best model after each epoch. This is my code: model = Sequential() model.add(LSTM(700, input_shape=(X_modified.shape[1], X_modified.shape[2]), return_sequences=True)) model.add(Dropout(0.2)) model.add(LSTM(700, return_sequences=True)) model.add(Dropout(0.2)) model.add(LSTM(700)) model.add(Dropout(0.2)) model.add(Dense(Y_modified.shape[1], activation='softmax')) model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy']) # Save the checkpoint in the

Reliability issues with Checkpointing/WAL in Spark Streaming 1.6.0

不问归期 提交于 2019-12-03 16:22:00
问题 Description We have a Spark Streaming 1.5.2 application in Scala that reads JSON events from a Kinesis Stream, does some transformations/aggregations and writes the results to different S3 prefixes. The current batch interval is 60 seconds. We have 3000-7000 events/sec. We’re using checkpointing to protect us from losing aggregations. It’s been working well for a while, recovering from exceptions and even cluster restarts. We recently recompiled the code for Spark Streaming 1.6.0, only

Stop and Restart Training on VGG-16

元气小坏坏 提交于 2019-12-02 05:12:25
I am using pre-trained VGG-16 model for image classification. I am adding custom last layer as the number of my classification classes are 10. I am training the model for 200 epochs. My question is: is there any way if I randomly stop (by closing python window) the training at some epoch, let's say epoch no. 50 and resume from there? I have read about saving and reloading model but my understanding is that works for our custom models only instead of pre-trained models like VGG-16. You can use ModelCheckpoint callback to save your model regularly. To use it, pass a callbacks parameter to the

I am building docker from this version of this source code: https://github.com/boucher/docker/tree/cr-combined after cloning the code : git clone -b cr-combined --single-branch https://github.com/boucher/docker.git cd docker #make build #make binary And then copied the resulting file @./bundles/../docker to the usr/bin directory After reopening the terminal and starting the docker engine again. its shows that i am using my own built version but This version should have two main docker commands that won't show up in my built one 1- checkpoint 2- restore could you please help me and tell me

Spark Checkpointing Non-Streaming - Checkpoint files can be used in subsequent job run or driver program

偶尔善良 提交于 2019-11-27 18:57:07
问题 This text from an interesting article: http://www.lifeisafile.com/Apache-Spark-Caching-Vs-Checkpointing/ " ... Checkpointing stores the rdd physically to hdfs and destroys the lineage that created it. The checkpoint file won’t be deleted even after the Spark application terminated. Checkpoint files can be used in subsequent job run or driver program. Checkpointing an RDD causes double computation because the operation will first call a cache before doing the actual job of computing and
