问题描述
假设我已经使用 TextLineReader
读取了文本文件。有什么方法可以在 Tensorflow
中将其分为训练集和测试集?
def read_my_file_format(filename_queue):
reader = tf.TextLineReader()
键, record_string = reader.read(filename_queue)
raw_features,label = tf.decode_csv(record_string)
features = some_processing(raw_features)
features_train,labels_train,featurestest,labelstest = tf.train_split(features,
标签,
frac = .1)
返回features_train,labels_train,features_test,labels_test
解决方案
类似下面的方法应该起作用:
tf.split_v(tf.random_shuffle(...
编辑:针对tensorflow> 0.12现在应将其称为 tf.split(tf.random_shuffle(...
请参阅,并以为例。 / p>
Let's say I've read in a textfile using a TextLineReader
. Is there some way to split this into train and test sets in Tensorflow
? Something like:
def read_my_file_format(filename_queue):
reader = tf.TextLineReader()
key, record_string = reader.read(filename_queue)
raw_features, label = tf.decode_csv(record_string)
features = some_processing(raw_features)
features_train, labels_train, features_test, labels_test = tf.train_split(features,
labels,
frac=.1)
return features_train, labels_train, features_test, labels_test
解决方案
Something like the following should work:tf.split_v(tf.random_shuffle(...
Edit: For tensorflow>0.12 This should now be called as tf.split(tf.random_shuffle(...
See docs for tf.split and for tf.random_shuffle for examples.
