squeeze every drop of the system, you have to face the scary world of pointers.Fortunately, the modern C + + + writing experience is good (honestly!). ）。 You can choose from one of the following methods: You can go to the bottom of the stack, use a library like CUDA to write your own code that will run directly on the GPU, or you can use TensorFlow or Caffe to access the flexible advanced API. The latter also allows you to import models written by data scientists in Python, and then run them in

Mxnet is the foundation, Gluon is the encapsulation, both like TensorFlow and Keras, but thanks to the dynamic graph mechanism, the interaction between the two is much more convenient than TensorFlow and Keras, its basic operation and pytorch very similar, but a lot of convenience, It's easy to get started with a pytorch foundation.Library import notation,From mxnet import Ndarray as Ndfrom mxnet import aut

Valueerror:negative dimension size caused by subtracting 3 from 1 The reason for this error is the problem with the picture channel.That is, "channels_last" and "Channels_first" data format problems.Input_shape= (3,150, 150) is the Theano, and TensorFlow needs to write: (150,150,3).

robust and generic model for your own projects:1. Tensorflow.js also released the Posenet, which may be an interesting way to use it. From the machine's point of view, tracking the position of the wrist, elbow, and shoulder in the picture should be enough to predict with most words. When you spell something, the position of the finger is often important.2. Using a CNN-based approach, such as the "Pac Man" example, can improve accuracy and make the model more resistant to translational invarianc

, just three computers instead of 1000, could do that, and the secret was to use GPU technology. So, Caffe in the original design concept, is the GPU as the core computing, CPU for auxiliary control and I/O framework.The compiler macro functionality provided by C/+ + enables Caffe to create code with different platform requirements by simply adding a single macro to the flexible mix programming.The latest version of Caffe, on the CPU and GPU, the balance is very good.
