pickle的loads报错a bytes-like object is required

当使用pickle的loads函数时，出现“a bytes-like object is required”错误是因为在打开pickle文件时使用了错误的模式。在Python 3中，使用'r'模式读取文件会返回一个字符串对象，而不是字节对象。因此，需要将模式更改为'rb'，以字节模式打开文件，然后使用pickle.load函数来加载pickle文件。这样就可以解决这个错误了。 例如，你可以使用以下代码来加载pickle文件：

with open('train_id.pickle', 'rb') as f:
    data = pickle.load(f)

这样就能够成功加载pickle文件并解决报错问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
