原创 常用matplotlib.pyplot画图系列（组）
1. 画两组数据的对比折线图import numpy as npimport matplotlib.pyplot as pltalist = [4,5,7,1,3,7,4,9,4,2] # 也可以是ndarray类型blist = [8,3,6,1,0,4,5,9,2,7]t_plt, = plt.plot(np.arange(1, len(alist)+1), alist, 'r

转载 tensorflow:用dynamic_rnn处理不定长序列，对序列做padding处理
1. 数据处理（padding zero）首先，我有一个list类型的数据集，按最长将序列的长度存储，不足长度的后面padding zero。将数据集存为ndarray类型的矩阵：import numpy as npdataset = [[[1], [2], [3], [4]], # list类型的数据集，有4个序列, feature_dim=1

原创 tensorflow：tf.stack的用法
堆叠list类型的数据：import tensorflow as tflist_ = [[1, 2, 3], [4, 5, 6]]print(type(list_))a = tf.stack(list_, 0)print(a.get_shape().as_list())输出结果：[2, 3]

原创 sklearn的precision_score, recall_score, f1_score使用
from sklearn.metrics import precision_score, recall_score, f1_scorey_true = [0, 1, 1, 0, 1, 0]y_pred = [1, 1, 1, 0, 0, 1]p = precision_score(y_true, y_pred, average='binary')r = recall_score(y_t

原创 tensorflow报错:Shape must be rank 2 but is rank 3 for 'MatMul' (op: 'MatMul')
tensorflow矩阵相乘，秩不同报错在tensorflow中写了这样一句：y_out = tf.matmul(outputs, W)其中，outputs的shape为[16,336,400]，W的shape为[400,1]出现以下报错：Shape must be rank 2 but is rank 3 for 'MatMul' (op: 'MatMul') with

原创 matplotlib.pyplot画灰度图
以画MNIST手写体为例：import matplotlib.pyplot as pltfrom tensorflow.contrib.learn.python.learn.datasets.mnist import read_data_setsmnist = read_data_sets('MNIST_data', one_hot=False)x, y = mnist.test.n
