拒绝访问用于训练深度学习模型的TFRecords的访问权限

Question

我正在使用Google QuickDraw数据集训练模型。我已经按照教程中的指示将数据从ndjson存储到tfrecords。然后，我使用Google link提供的代码使用这些tfrecords训练数据集。但我收到以下错误：

Traceback (most recent call last):

我没有确切地知道哪个函数正在给出错误。因此，我尚未发布代码，因为我不知道代码的相关部分。但是为什么拒绝访问？我使用了与存储库中几乎相同的代码。另外，我没有得到错误的根源，仅仅是访问被拒绝还是其他？请帮助我。

Answer 1

请确保您正在访问的文件具有正确的扩展名".tfrecords"。

当尝试访问的文件没有正确的扩展名时，会发生此问题。
