  • Tensorflow implementation output intermediate value with tf.print in function

    Time:2020-4-1

    Tensorflow is based on static graph mode, which makes it difficult to debug when writing code. In addition to using official debugging tools, the most direct way is to output the intermediate results for viewing. However, directly using print function can only output the shape of the sensor variable, not the value. If you want […]

  • Tensorflow to print the output of each layer

    Time:2020-3-30

    In test.py, you can directly generate a Pb file with weight through the following code, or you can convert CKPT to a Pb file through TF’s official free graph.py. constant_graph = graph_util.convert_variables_to_constants(sess, sess.graph_def,[‘net_loss/inference/encode/conv_output/conv_output’]) with tf.gfile.FastGFile(‘net_model.pb’, mode=’wb’) as f: f.write(constant_graph.SerializeToString()) In tf1.0, the output of each layer can be obtained through the Pb file with weight […]

  • How to use the. Pb file of tensorflow training in production environment

    Time:2020-3-10

    Preface Tensorflow is an open-source artificial intelligence learning system of Google. Why is it called that? Tensor means tensor, representing n-dimensional array; flow means flow, representing calculation based on data flow graph. The process of moving n-dimension numbers from one end of flow graph to the other is the process of analysis and processing by […]

  • Learning notes tf007: tensor, graph, Op, variable, placeholder, session, name scope, board comprehensive example

    Time:2020-2-8

    The input adopts placeholder, the model receives any length vector, calculates the total output of data flow graph over time, reasonably divides the data flow graph by name scope, saves the output, accumulation and mean value of data flow graph to disk every time. [none] for any length vector, [] for scalar. The update phase […]

  • Tensorflow: natural style

    Time:2020-2-5

    Neural style is a very interesting deep learning application: input a picture representing the content and a picture representing the style, and the deep learning network will output a new work integrating the style and content. Tensorflow is Google’s most popular open source deep learning framework. Author anishatalye uses tensorflow to implement the neural style […]

    Time:2020-2-3

    Why write At first, I thought that it was very convenient to install tensorflow. After the installation, it took me two days. There was no other explanation except carelessness. Don’t say that my IQ was low. I knew it myself… Tensorflow is really powerful after the update. It exceeds a series of in-depth learning frameworks […]
