这个错误是由于你使用的 Keras 版本不支持 TensorFlow 2.0 导致的。建议你使用 tf.keras 或者将 TensorFlow 版本降级到 1.14。你可以尝试在代码中使用以下语句来切换到 tf.keras:
```python
from tensorflow import keras
```
然后使用 `keras` 而非 `keras.backend`。如果你需要使用 `keras.backend`,可以这样导入:
```python
from tensorflow.keras import backend as K
```
这样就可以避免使用旧版的 Keras。

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0. If you cannot immediately regenerate your protos, some other possible workarounds are: 1. Downgrade the protobuf package to 3.20.x or lower. 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

根据错误信息,这个问题是由于你的生成的代码(`_pb2.py`文件)与你安装的protobuf版本不兼容导致的。
根据错误提示,你需要重新生成你的protobuf代码,使用protoc版本大于等于3.19.0来进行生成。这样可以确保生成的代码与你安装的protobuf版本兼容。
你可以按照以下步骤重新生成protobuf代码:
1. 确保你已经安装了最新版本的protobuf。你可以使用以下命令来升级protobuf:
```
pip install --upgrade protobuf
```
2. 确保你已经安装了protoc编译器,并且其版本大于等于3.19.0。你可以在命令行中运行以下命令来检查protoc版本:
```
protoc --version
```
如果protoc版本低于3.19.0,请更新到最新版本。你可以在Protocol Buffers的官方网站上找到适合你操作系统的安装包。
3. 使用更新后的protoc编译器重新生成protobuf代码。在命令行中运行以下命令:
```
protoc -I=<proto文件目录> --python_out=<生成代码目录> <proto文件>
```
其中,`<proto文件目录>`是包含proto文件的目录,`<生成代码目录>`是你想要生成代码的目录,`<proto文件>`是你要生成代码的proto文件名。
重新生成protobuf代码后,再运行你的程序,应该就能够解决这个问题了。如果问题仍然存在,你可以尝试降级protobuf包的版本,或者设置`PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python`环境变量来使用纯Python解析,但后者会导致解析速度较慢。
请确保按照官方文档中提供的链接获取更多信息,并根据你的具体情况进行调整。

根据您提供的错误信息,出现了两个异常:IndexError和ClientError。IndexError表示连接池中没有可用的连接,而ClientError表示由于身份验证失败而导致未经授权的客户端。
解决这些问题的步骤如下:
1. 确保您提供的Neo4j数据库URL和凭据是正确的。检查URL中的主机名、端口号以及凭据的用户名和密码是否与您在Neo4j中设置的一致。
2. 确保Neo4j数据库正在运行并监听正确的端口。您可以尝试通过浏览器访问Neo4j的管理界面来验证数据库是否可用。
3. 检查防火墙设置,确保允许连接到Neo4j数据库所使用的端口。
4. 如果您在使用用户名和密码进行身份验证时仍然遇到问题,可以尝试更改身份验证方法。例如,您可以尝试使用Kerberos或LDAP进行身份验证,具体取决于您在Neo4j中的配置。
5. 确保您的py2neo库版本是最新的。您可以使用以下命令升级py2neo库:
```
pip install --upgrade py2neo
```
如果问题仍然存在,请检查您的代码是否有其他问题,并考虑向Neo4j社区寻求更多帮助。
