AttributeError：“tensorflow.python.framework.ops.EagerTensor”对象没有属性“to_tensor”

Question

我正在使用 Hugging Face、Keras、Tensorflow 库微调 BERT 模型。

从昨天开始，我在 Google Colab 中运行我的代码时遇到了这个错误。奇怪的是，以前运行的代码没有任何问题，突然开始抛出这个错误。更令人怀疑的是，代码在我的 Apple M1 tensorflow 配置中运行没有问题。同样，我没有对我的代码进行任何更改，但现在代码无法在 Google Colab 中运行，尽管它过去运行时没有任何问题。

两个环境都有 tensorflow 2.6.0

我创建了以下代码以重现错误。我希望你能对此有所了解。

!pip install transformers
!pip install datasets

import pandas as pd
import numpy as np
import tensorflow as tf
from transformers import AutoTokenizer
from datasets import Dataset

# dummy sentences
sentences = ['the house is blue and big', 'this is fun stuff','what a horrible thing to say']

# create a pandas dataframe and converto to Hugging Face dataset
df = pd.DataFrame({'Text': sentences})
dataset = Dataset.from_pandas(df)

#download bert tokenizer
tokenizer = AutoTokenizer.from_pretrained('bert-base-uncased')

# tokenize each sentence in dataset
dataset_tok = dataset.map(lambda x: tokenizer(x['Text'], truncation=True, padding=True, max_length=10), batched=True)

# remove original text column and set format
dataset_tok = dataset_tok.remove_columns(['Text']).with_format('tensorflow')

# extract features
features = {x: dataset_tok[x].to_tensor() for x in tokenizer.model_input_names}

Answer 1

删除to_tensor() 后，给定代码按照@Harold G 的建议工作。

!pip install transformers
!pip install datasets

import pandas as pd
import numpy as np
import tensorflow as tf
from transformers import AutoTokenizer
from datasets import Dataset

# dummy sentences
sentences = ['the house is blue and big', 'this is fun stuff','what a horrible thing to say']

# create a pandas dataframe and converto to Hugging Face dataset
df = pd.DataFrame({'Text': sentences})
dataset = Dataset.from_pandas(df)

#download bert tokenizer
tokenizer = AutoTokenizer.from_pretrained('bert-base-uncased')

# tokenize each sentence in dataset
dataset_tok = dataset.map(lambda x: tokenizer(x['Text'], truncation=True, padding=True, max_length=10), batched=True)

# remove original text column and set format
dataset_tok = dataset_tok.remove_columns(['Text']).with_format('tensorflow')

# extract features
features = {x: dataset_tok[x] for x in tokenizer.model_input_names}
