FutureWarning: Calling BertTokenizer.from_pretrained() with the path to a single file or url is deprecated and won't be possible anymore in v5. Use a model identifier or the path to a directory instead. FutureWarning,

这个 FutureWarning 是由于你使用的 BertTokenizer.from_pretrained() 方法的参数传递方式不再被支持，建议使用模型标识符或目录路径替代单个文件或 URL 的方式。这个警告是为了提醒你在未来版本的代码中需要修改这部分代码，以免出现错误。建议你按照警告的建议进行修改，这样可以保证代码的可靠性和稳定性。

calling RandomUniform.__init__ (from tensorflow.python.ops.init_ops) with dtype is deprecated and will be removed in a future version.

This warning message is indicating that using the `dtype` argument in the `RandomUniform.__init__` function from `tensorflow.python.ops.init_ops` is deprecated and will be removed in a future version of TensorFlow.

To resolve this issue, you should omit the `dtype` argument when calling the `RandomUniform` initializer. The dtype will be automatically inferred from the variable or tensor being initialized.

Here's an example of how to use `RandomUniform` initializer without specifying the `dtype`:

import tensorflow as tf

initializer = tf.keras.initializers.RandomUniform(minval=-1.0, maxval=1.0)

Make sure to update your code accordingly to remove the `dtype` argument in the `RandomUniform` initializer call.

WARNING:tensorflow:From E:\machine_learning\tensorflow2\envs\tf1\lib\site-packages\tensorflow\python\ops\resource_variable_ops.py:1666: calling BaseResourceVariable.__init__ (from tensorflow.python.ops.resource_variable_ops) with constraint is deprecated

你好！关于你的问题，这是一个关于 的警告信息。这个警告是由于使用了被弃用的约束(constraint)参数导致的。约束参数在 TensorFlow 2.x 版本中已经被移除，如果你的代码中使用了约束参数，建议更新代码以适应最新的 TensorFlow 版本。如果你需要进一步的帮助，请提供更多的上下文信息。
