gradient

问题 I am using python 3 with anaconda, and tensorflow 1.12 with eager eval. I am using it to create a triplet loss function for a siamese network, and need to calculate distance between different data samples. I created a function in order to create the distance calculation, but no matter what I do, when I try to calculate it's gradient with respect to the networks output, It keeps giving me all nan gradient. This is the code: def matrix_row_wise_norm(matrix): import tensorflow as tf tensor = tf

问题 I want to create text with linear gradient color in react-native, but cannot find a suitable way or package to do this. I tried to use this package : https://github.com/iyegoroff/react-native-text-gradient. But, while trying to run an example with expo, it is giving me the following error : TypeError: Cannot read property 'x' of undefined This error is located at: in RNLinearTextGradient (at App.js:26) in RCTView (at View.js:60) in View (at App.js:17) in App (at registerRootComponent.js:35)

问题 I'm building an application and I want to create an effect similar to this in a ListView. https://css-tricks.com/recreating-the-facebook-messenger-gradient-effect-with-css/ If I would know the widget's position in the build method, I could calculate the gradient of the widget. After the widget is rendered, I can get the position of the widget by a GlobalKey that is assigned to the widget in the build method. This approach isn't working in my case, because I need the position in order to
