ImportError: cannot import name 'distances' from 'pytorch_metric_learning'

这个错误通常是由于未安装或不兼容的版本导致的。请检查您是否已经正确安装了 `pytorch_metric_learning` 库，并且版本是否与您的代码兼容。您可以通过运行以下命令来安装最新版本的 `pytorch_metric_learning` 库：

pip install pytorch_metric_learning --upgrade

如果您已经安装了 `pytorch_metric_learning` 库，但仍然遇到该错误，请尝试使用以下命令卸载并重新安装该库：

pip uninstall pytorch_metric_learning
pip install pytorch_metric_learning

如果以上方法仍然无法解决问题，请检查您的代码是否正确导入了 `distances` 模块，并且该模块是否存在。您可以尝试手动导入该模块并检查是否存在问题：

from pytorch_metric_learning import distances

如果仍然无法解决问题，请提供更多详细信息，以便我更好地帮助您解决问题。

ImportError: cannot import name 'distances' from 'pytorch_metric_learning' (/home/image/anaconda3/envs/yxg/lib/python3.7/site-packages/pytorch_metric_learning/__init__.py)

这个错误是由于在 `pytorch_metric_learning` 包中找不到 `distances` 模块而导致的。你可以尝试检查 `pytorch_metric_learning` 包是否已经正确安装，并且确保你的代码中正确引用了这个模块。如果问题仍然存在，可以尝试升级或者降级 `pytorch_metric_learning` 包以解决该问题。

ImportError: cannot import name 'rank_zero_only' from 'pytorch_lightning.utilities.distributed'

This error typically occurs when you are trying to import the `rank_zero_only` function from the `pytorch_lightning.utilities.distributed` module, but the function cannot be found.

This could be due to a few different reasons:

1. You may be using an outdated version of PyTorch Lightning that does not include the `rank_zero_only` function. Try updating to the latest version.

2. You may have misspelled the function name or the module name. Double-check that you are importing the correct function from the correct module.

3. It's possible that the `pytorch_lightning.utilities.distributed` module is not installed properly or is corrupted. Try reinstalling PyTorch Lightning and see if the issue persists.

4. There could be a conflict between different versions of PyTorch or other dependencies. Try creating a new virtual environment and installing only the required packages for your project.

If none of these solutions work, you may want to post a more detailed question with code snippets and error messages to get more specific help.
