[Bug]: Dependency conflict with Pillow version

[11296925]

What happened?

While using autogen-agentchat (v0.4.2) and fastembed (v0.5.1) together in a Poetry-managed project, there is a version conflict due to incompatible pillow version constraints.

• autogen-agentchat requires pillow >=11.0.0
• fastembed requires pillow >=10.3.0,<11.0.0

This results in dependency resolution failure when trying to install both packages.

What is the expected behaviour?

Would be ideal to be able to use both dependencies by having the newest version of Pillow available in the dependencies of fastembed.

A minimal reproducible example

pyproject.toml

[tool.poetry.dependencies]
python = "3.11.9"
fastembed = "^0.5.1"
autogen-ext = { version = "0.4.2", extras = ["openai", "azure"] }
pillow = ">=10.3.0,<11.0.0" # Optional for fastembed

What Python version are you on? e.g. python --version

Python3.11.9

FastEmbed version

v0.5.1

What os are you seeing the problem on?

No response

Relevant stack traces and/or logs

Because no versions of fastembed match >0.5.1,<0.6.0
 and fastembed (0.5.1) depends on pillow (>=10.3.0,<11.0.0), fastembed (>=0.5.1,<0.6.0) requires pillow (>=10.3.0,<11.0.0).
And because autogen-agentchat (0.4.2) depends on autogen-core (0.4.2) which depends on pillow (>=11.0.0), fastembed (>=0.5.1,<0.6.0) is incompatible with autogen-agentchat (0.4.2).
So, because app depends on both autogen-agentchat (0.4.2) and fastembed (^0.5.1), version solving failed.
