@Wendong-Fan please have a look, thanks.

Hey @iamsk , thanks for bringing up the issue. It seems this problem arose because the CAMEL package was updated, but the code in the cookbook wasn't aligned with the new version. You can quickly fix this by running
pip install camel-ai[all]==0.1.6.0 when install CAMEL package
