cannot import name 'amp_state' from 'paddle.amp.auto_cast' (/usr/local/lib/python3.7/dist-packages/paddle/amp/auto_cast.py)

This error message suggests that there is an import error in your code. Specifically, it is unable to import the 'amp_state' function from the 'paddle.amp.auto_cast' module.

There are several possible reasons for this error:

1. The 'amp_state' function may not be defined in the 'paddle.amp.auto_cast' module. Double-check the documentation to ensure that the function exists in the module.

2. The version of PaddlePaddle you are using may not support the 'amp_state' function. Try upgrading to the latest version of PaddlePaddle.

3. There may be a typo or other syntax error in your code that is preventing the import from working correctly. Review your code carefully to ensure that it is correct and complete.

4. There may be a conflict with other modules or packages that you have installed. Try uninstalling any unnecessary packages and see if the error persists.

If none of these solutions work, you may need to seek further help from the PaddlePaddle community or support team.
