Question

我在法语中使用 Bert 标记器，我收到此错误，但我似乎没有解决它。如果您有任何建议。


Traceback (most recent call last):

ValueError: Input is not valid. Should be a string, a list/tuple of strings or a list/tuple of integers.

我环顾四周寻找喜欢的答案，但提出的建议似乎不起作用。文本是数据框。

这里是代码：

def get_flaubert_layer(texte): # teste is dataframe which I take from an excel file
    
    language_model_dir= os.path.expanduser(args.language_model_dir)
    lge_size = language_model_dir[16:-1]   # modify when on jean zay 27:-1
    print(lge_size)
    flaubert = FlaubertModel.from_pretrained(language_model_dir)
    flaubert_tokenizer = FlaubertTokenizer.from_pretrained(language_model_dir)
    tokenized = texte.apply((lambda x: flaubert_tokenizer.encode(x, add_special_tokens=True, max_length=512, truncation=True)))
    max_len = 0
    for i in tokenized.values:
        if len(i) > max_len:
            max_len = len(i)
    padded = np.array([i + [0] * (max_len - len(i)) for i in tokenized.values])
    attention_mask = np.where(padded != 0, 1, 0)

我有另一个结构相同的文件，但它可以工作，但对于这种情况，我不知道为什么我应该重新下载模型会出现此错误？

您可能想要更改此行：

tokenized = texte.apply((lambda x: flaubert_tokenizer.encode(x, add_special_tokens=True, max_length=512, truncation=True)))

到

tokenized = flaubert_tokenizer.encode(texte["verbatim"], 
    add_special_tokens=True, 
    max_length=512, 
    truncation=True)`

这有两个优点：

您没有将 Pandas 行传递给标记化函数（我猜这是导致您出错的原因）。
您不是每行调用一次 encode 函数。这可能会加速标记化。

“输入无效。应该是字符串、字符串列表/元组或整数列表/元组。”值错误：输入无效
