题意：在 OpenAI 的助手（assistants）中，“Assistants” 没有 “files” 这个属性。

问题背景：

assistant_file = client.beta.assistants.files.create(
    assistant_id = st.session_state.assistant_id,
    file_id = st.session_state.file_id
)

I have this code which I have to integrate but it's showing up that "Assistants" have no attribute "file", this code is around 8 months old, and I understand that the API probably changed since then, but I cannot find any alternatives to this in the documentation. Does anyone have any experience in migrating this code ?

我有这段代码需要集成，但是它显示“Assistants”没有“file”这个属性。这段代码大约有8个月的历史了，我理解从那时起API可能已经发生了变化，但我在文档中找不到关于这个问题的替代方案。有人有迁移这段代码的经验吗？

问题解决：

The method you're trying to use (i.e., .files.create) doesn't exist.

你试图使用的方法（即 .files.create）不存在。

Moreover, this code wouldn't work even with the OpenAI Assistants API v1.

此外，即使使用 OpenAI Assistants API v1，这段代码也无法工作。

If you want to create an assistant, use the following code (works with the OpenAI Assistants API v2):

如果你想要创建一个助手，请使用以下代码（适用于 OpenAI Assistants API v2）：

from openai import OpenAI
client = OpenAI()

my_assistant = client.beta.assistants.create(
    instructions="You are a personal math tutor. When asked a question, write and run Python code to answer the question.",
    name="Math Tutor",
    tools=[{"type": "code_interpreter"}],
    model="gpt-4o",
)

print(my_assistant)

If you want to create a file for an assistant, use the following code (works with the OpenAI Assistants API v2):

如果你想要为助手创建一个文件，请使用以下代码（适用于 OpenAI Assistants API v2）：

from openai import OpenAI
client = OpenAI()

my_file = client.files.create(
  file=open("mydata.jsonl", "rb"),
  purpose="assistants"
)

print(my_file)
