Python:类型错误“ float”对象不可迭代

我的代码是:

for ep in range(10):
    for x, y in tqdm(train_iterator.gen_batches(batch_size=64, 
                                           data_type="train")):
        x_embed = embedder(tokenizer(str_lower(x)))
        y_onehot = onehotter(classes_vocab(y))
        cls.train_on_batch(x_embed, y_onehot)

和结果:

<ipython-input-30-3f8c38399ce9> in <module>()
      2     for x, y in tqdm(train_iterator.gen_batches(batch_size=64, 
      3                                            data_type="train")):
----> 4         x_embed = embedder(tokenizer(str_lower(x)))
      5         y_onehot = onehotter(classes_vocab(y))
      6         cls.train_on_batch(x_embed, y_onehot)

     31         return batch.lower()
     32     else:
---> 33         return list(map(str_lower, batch))

TypeError: 'float' object is not iterable

我试图将其更改为ep = int [float],但这也不起作用。

1 个答案:

答案 0 :(得分:0)

str_lower()将字符串作为参数或可迭代类型,然后在其上调用.lower()。但是,在您的代码中,x的类型为float。 因此,每当以list()作为参数调用x时,都会返回此错误:

>>> list(3.14)
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    list(3.14)
TypeError: 'float' object is not iterable

所以您要么想要:

  • 确保x是字符串
  • 不打str_lower(x)
