TypeError: Client.__init__() got an unexpected keyword argument 'proxies' [Google Colab]

Bug description

TypeError: Client.__init__() got an unexpected keyword argument 'proxies'

In colab notebooks adalflow library's OpenAIClient still attempting to pass the proxies keyword argument during the initialization of the OpenAI client from the openai library. Newer versions of the openai library have removed the proxies argument from their Client.init method. The problem is with the new version of the httpx library which openai and other clients use

The solution is downgrading httpx but doing just that causes dependency conflicts so what we need to do is update multiple packages and versions.

Bug Hypothesis: Dependency Conflict Resolution in Different Environments

Observed Behavior:

• Local environment: Code works fine with:

  • anyio 4.4.0
  • httpx 0.27.0
  • httpx-sse 0.4.0
  • jupyter-server 2.14.2
  • jupyter-server-terminals 0.5.2

• Colab environment: Code fails with dependency conflict requiring manual downgrade

  • Error indicates jupyter-server 1.24.0 requiring anyio < 4.0

Root Cause Analysis:
The core issue appears to be version mismatching between environments. While the local setup uses a newer jupyter-server (2.14.2) that's compatible with anyio 4.x, Colab is locked to an older jupyter-server version (1.24.0) that explicitly requires anyio < 4.0.

Supporting Evidence:

1. Local environment shows newer versions working harmoniously (jupyter-server 2.14.2)
2. Colab environment errors specifically mention jupyter-server 1.24.0's constraint
3. The fix (downgrading anyio and then installing httpx) works consistently in Colab

Conclusion:
This isn't actually a bug in the code, but rather an environment-specific dependency constraint. The local environment's newer jupyter-server version allows for newer anyio versions, while Colab's older jupyter-server forces us to maintain compatibility with older anyio versions.

Solution is to add these commands after installing adalflow

!pip uninstall httpx anyio -y
!pip install "anyio>=3.1.0,<4.0"
!pip install httpx==0.24.1
