python - 使用 Streamlit 和 Langchain 构建在线 AutoGPT 应用程序时出错

Question

我在尝试将 LangChain 与 Streamlit 结合使用来构建在线 AutoGPT 应用程序时收到此错误。

input to Terminal:

streamlit run /Users/*username*/opt/anaconda3/lib/python3.9/site-packages/ipykernel_launcher.py

returns:

Traceback (most recent call last):

如果有人能指出我正确的方向，我将不胜感激!

检查您是否安装了最新版本的 Streamlit 和 Google Protocol Buffers。您可以使用以下命令来升级这两个软件包:

pip install --upgrade streamlit
pip install --upgrade protobuf

如果问题仍然存在，可能是由于不同版本的 Google Protocol Buffers 库之间存在冲突。这种情况，您可以尝试卸载并重新安装protobuf包:

pip uninstall protobuf
pip install protobuf

我也遇到了类似的问题，也许两个包不兼容，这就是我的问题。我会看看是否有彼此不兼容的软件包

祝你好运=)
