[BUG] AuthenticationError of creating an OpenAIEmbedding Instance when utilize an OpenAI proxy service

[Tsumugii24]

Required prerequisites

• I have read the documentation https://camel-ai.github.io/camel/camel.html.
• I have searched the Issue Tracker and Discussions that this hasn't already been reported. (+1 or comment there if it has.)
• Consider asking first in a Discussion.

What version of camel are you using?

0.1.6.9

System information

3.10.14 | packaged by Anaconda, Inc. | (main, May 6 2024, 19:44:50) [MSC v.1916 64 bit (AMD64)] win32
0.1.6.9

Problem description

AuthenticationError will be raised when creating an OpenAIEmbedding instance when utilize an OpenAI proxy service.
To be more specific, the key argument OPENAI_API_BASE_URL is not considered in openai_embedding.py.

Reproducible example code

The Python snippets:

from camel.embeddings import OpenAIEmbedding

openai_api_key = "your api key"
openai_base_url = "your base url"
os.environ["OPENAI_API_KEY"] = openai_api_key
os.environ["OPENAI_API_BASE_URL"] = openai_base_url

embedding_model=OpenAIEmbedding()
text = "camel"
vector = embedding_model.embed(text)

Command lines:

You can find your API key at https://platform.openai.com/account/api-keys.', 'type': 'invalid_request_error', 'param': None, 'code': 'invalid_api_key'}}

Steps to reproduce:

1. set OPENAI_API_KEY and OPENAI_API_BASE_URL
2. create an instance of OpenAIEmbedding
3. call its embed method

Expected behavior

If I set os.environ["OPENAI_API_BASE_URL"] in the environment variables, then after instantiating OpenAIEmbedding(), it can be used directly. Alternatively, a new optional url parameter can be added, allowing the user to manually specify it when instantiating the embedding model, such as OpenAIEmbedding(url="your base url").

Additional context

No response
