将高斯噪声添加到所有张量流变量

I'm working on a project which needs to evaluate the performance of CNN/RNN after adding noise to all the variables. For example, if we have an simple MLP, I want to add a random gaussian noise to all the weight parameters, which is not difficult. However, it doesn't seem easy to manipulate the variables for RNN. For example, the variables inside the I'm working on a project which needs to evaluat
