Problem

Today when I running a Keras program with Tensorflow backend, the following error message unexpectedly occurred:

[Solved] FutureWarning: Passing (type, 1) or ‘1type’ as a synonym of type is deprecated; in a future version of numpy, it will be understood as (type, (1,)) / ‘(1,)type’. _np_qint8 = np.dtype([(“qint8”, np.int8, 1)])

Tensorflow can be said to be the most well-known among the many deep learning framework, but when I use Keras/Tensorflow, I often encounter the following FutureWarning about the Numpy version:

Introduction

I have been studying about pointer-generator network lately, and I found a package “pkbar“can let us to use keras style progress bar in our tasks.

In fact, it can be used not only in the code of PyTorch framework but also in any loop.

Introduction

Google Colab, its full name is “Google colaboratory”, as the name suggests, it’s a service provided by Google. The advantage of Colab is that it provides a free GPU. Although you can only use the time limit of 12 hours a day, and the model training too long will be considered to be dig in the cryptocurrency.
