The Ndarrray in List/tuple,numpy in Python and the tensor in TensorFlow.In Python, List/tuple understands that a sequence of data is understood only from the memory point of view, not the number of mathematical bids, vectors, and tensor.From the Python memory point of view, is a numeric value, length 1, and is not a sequence;From the perspective of NumPy and TensorFlow mathematics, it is a scalar, shape is (), its axis is 0;[1,2,3,4,5,6]From the Pytho

Objective Some time ago because the subject needs to use a period of time tensorflow, feel this framework is very interesting, in addition to can build complex neural network, but also can optimize the other needs of the calculation model, so I always want to learn to write a similar diagram calculation framework. In the last few days, the group will finish the decision to implement a rough version diagram computing framework that mimics the

In the deep learning network structure, the categories of each layer can be divided into these kinds: convolution layer, full connection layer, Relu layer, pool layer and reverse convolution layer. At present, in pixel-level estimation and end-to-end learning problems, full convolution network shows his advantage, there is a very important layer, the convolution of the feature map sampling (deconvolution) to the input image dimension space, is the deconvolution layer. So how does it come to be a

the cause of the problem Today, try to install the CPU version of TensorFlow (GPU is not supported) by PIP3 install TensorFlow installation. The installation went well and I ran the simplest Hello wolrd example. The results do run out and a warning pops up. 2017-11-28 09:07:17.849180:i tensorflow/core/platform/cpu_feature_guard.cc:137] Your CPU supports instru

TensorFlow and Theano and Keras are deep learning frameworks, TensorFlow and Theano are more flexible and difficult to learn, they are actually a differentiator. Keras is actually TensorFlow and Keras interface (Keras as the front end, TensorFlow or Theano as the back end), it is also very flexible, and relatively eas

TensorFlow model save/load When we use an algorithmic model on-line, we must first save the trained model. TensorFlow the way to save the model is not the same as Sklearn, Sklearn is straightforward, a sklearn.externals.joblib dump and load method can be saved and loaded using. and TensorFlow because of the graph, operation these concepts, save and load the mode
