1. 预加载数据 Preloaded data # coding: utf-8 import tensorflow as tf # 设计Graph x1 = tf.constant([2, 3, 4]) x2 = tf.constant([4, 0, 1]) y = tf.add(x1, x2) with tf.Session() as sess: print sess.run(y) # output: # [6 3 5] 预加载数据方式是将训练数据直接内嵌到tf的图中,需要提前将数据加载到内存…

比如读取数据时想把第一列设为index,那么只需要简单的 pd.read_csv("new_wordvecter.csv",index_col=[0]) 这里index_col可以设为列名 后续更改index可以使用df.index = df.iloc[:,"column"].tolist()或df.set_index('column')…
