这个错误是由于在生成动态消息类型时发生了语法错误。根据错误提示,有一个类名为"___apollo.test.CaseSample"的消息类型生成时出现了无效的语法。可能有几个原因导致这个错误:
1. 类名中包含了无效字符或特殊字符。
2. 类名中使用了保留字或关键字。
3. 类名中存在语法错误。
请检查生成动态消息类型的代码,并确保类名的语法正确,不包含无效字符或特殊字符,并且不使用保留字或关键字作为类名。如果仍然存在问题,请提供生成动态消息类型的代码,以便我能更好地帮助你解决问题。

这个报错是因为你的代码中使用了 TensorFlow,但是你的环境中没有安装 TensorFlow。
解决这个问题的方法是安装 TensorFlow 到你的环境中。你可以通过以下步骤来安装 TensorFlow:
1. 打开终端或命令行窗口。
2. 激活你的 Anaconda 环境,可以使用命令:`conda activate py39`。
3. 运行以下命令来安装 TensorFlow:
```
pip install tensorflow
```
如果你需要安装特定的版本,可以使用以下命令:
```
pip install tensorflow==<version>
```
注意,这里的 `<version>` 是指你希望安装的 TensorFlow 版本号。
4. 等待安装完成。安装完成后,你就可以重新运行你的代码了。
请确保按照上述步骤正确安装了 TensorFlow,并且在运行代码之前激活了正确的 Anaconda 环境。如果问题仍然存在,请提供更多关于你的代码和环境的详细信息,以便我能够更好地帮助你解决问题。

这个错误提示是由于 pandas 在读取 csv 文件时,无法正确地分隔数据。具体来说,它在读取第二行时期望只有一个字段,但实际上有三个字段。这通常是因为数据中包含了一些不规则的内容,例如特殊字符或文本中的逗号。建议你检查一下数据文件,确保每行的字段数都是一致的,并且没有不必要的空格或特殊字符。另外,你可以尝试使用不同的分隔符或引号字符来读取数据,以便正确地解析文件。
