所以我在jupytor笔记本中实现了RNN字生成器模型。 当我尝试使用训练过的模型生成一些单词时:
with open(os.path.join(cfgs['save_dir'], 'config.pkl'), 'rb') as f:
saved_args = cPickle.load(f)
with open(os.path.join(cfgs['save_dir'], 'words_vocab.pkl'), 'rb') as f:
words, vocab = cPickle.load(f)
with tf.Session() as sess:
model = Model(saved_args, True)
tf.global_variables_initializer().run()
saver = tf.train.Saver(tf.global_variables())
ckpt = tf.train.get_checkpoint_state(cfgs['save_dir'])
if ckpt and ckpt.model_checkpoint_path:
saver.restore(sess, ckpt.model_checkpoint_path)
print(model.sample(sess, words, vocab, cfgs['n'], cfgs['prime'], cfgs['sample'], cfgs['pick'], cfgs['width']))
它首次运行,但如果我再次运行代码则会出现错误:
ValueError: Variable rnnlm/softmax_w already exists, disallowed. Did you mean to set reuse=True in VarScope?
现在我必须关闭ipynb文件然后运行代码以获取新样本。 如何更改代码以避免这种情况?
答案 0 :(得分:1)
您可以多次调用model.sample函数而不会出现问题,但其他所有内容(创建会话,构建模型,加载检查点)应该只运行一次。如果您重构代码,那么您将不再看到该错误消息。
