推荐序二

I am happy to hear that Eric Zhang wrote a book covering object detection using TensorFlow.He knows how to quickly develop a solution based on the Neural Network using the high level frameworks like TensorFlow which otherwise would have required many more lines of code.The book also covers an end to end development cycle of a Deep Learning neural network and it will be very useful for the readers who are interested in this topic.Writing a book requires an extensive amount of effort and he finally completed it.Congratulations to Eric and all the readers who will gain a lot of useful knowledge from this book as well!
