这个错误提示是证书验证失败导致的,可能是因为您的 Python 环境缺少 SSL 模块。您可以尝试更新 OpenSSL、重新安装 Python 或安装 SSL 模块来解决这个问题。
如果您使用的是 Python 2.x 版本,可以使用以下命令安装 SSL 模块:
```
pip install pyopenssl ndg-httpsclient pyasn1
```
如果您使用的是 Python 3.x 版本,可以使用以下命令安装 SSL 模块:
```
pip3 install pyopenssl ndg-httpsclient pyasn1
```
如果您使用的是 Windows 操作系统,还需要在安装 Python 时选择“Install Certificates”选项,以确保 SSL 证书能够正确安装。

As an AI language model, I do not have access to the specific details of your system and the error message. However, this error message usually occurs when there is an issue with the SSL certificate on the server-side. Here are some possible solutions that you can try:
1. Check your internet connection and try again
2. Upgrade pip to the latest version using the following command: `pip install --upgrade pip`
3. Use the `--trusted-host` option with pip to ignore SSL errors: `pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org tensorflow`
4. Try installing the package with `conda` instead of `pip`
5. Update your SSL certificate bundle by downloading the latest version from the certifi package: `pip install --upgrade certifi`
6. If you are behind a corporate firewall, contact your IT department to check if there are any restrictions on SSL connections.
If none of the above solutions work, please provide more details about your system and the error message for further assistance.
