Permission Denied Error on Windows

[Nneji123]

When using the qa example code from the cookbook repo, uploading a file results in a Permission Denied error.

Also there is a file size upload limit of 2MB. Is there a way to disable this feature?

For the max file size you can use the max_size_mb parameter in ask_for_file, see https://docs.chainlit.io/api-reference/ask/ask-for-file

For the permission error that looks like a langchain error at first glance. Not sure that is the issue but could you try running the chainlit run command in a terminal with admin permissions?

[willydouhard]

Also can you try to run chainlit run without the -w option?

[Nneji123]

I tried both options(running a terminal with admin permissions and without the -w flag) and still got the same error. Tested this on a Linux cloud environment though and it works as expected.

Could you try to:

1. install chainlit from the wheel provided in this PR https://github.com/Chainlit/chainlit/pull/40
2. run chainlit hello

I would like to see if the rework fix those issues. Note that this version is not merged yet. The infos to install are at the end of the PR's description.

[willydouhard]

Should be fixed in the latest version 0.3.0. Please note that it contains breaking changes. We prepared a migration guide to make it easy for everyone.

I am facing the same issue, My code is pretty much the same as the example given at https://docs.chainlit.io/api-reference/ask/ask-for-file I tried running as admin, and also without the -w:

async def start():
    await cl.Message(content="Upload a file to chat with your file").send()
    files=None
    while files is None:
        files=await cl.AskFileMessage(
            content=welcome_message,
            accept=['text/plain','application/pdf'],
            max_size_mb=20,
            timeout=180
        ).send()

    file=files[0]
    # file=file.content.decode("utf-8")
    msg=cl.Message(content=f"Processing {file.name}...")
    await msg.send()

    docsearch = await cl.make_async(get_docsearch)(file)

    chain = RetrievalQAWithSourcesChain.from_chain_type(
        ChatOpenAI(temperature=0.8,
                   streaming=True,
                   chain_type="stuff",
                   retriever=docsearch.as_retriever(max_tokens_limit=4097)
                   )
        )

I think the problem is about python temp files on windows. You can avoid using temp files. Also would be helpful to search if there is a clean solution for this

[brahmapsen]

Yes, it is the problem of Python writing to Temp directory. I had the code like below:

with tempfile.NamedTemporaryFile() as tempfile: tempfile.write(file.content) loader = Loader(tempfile.name)

It was giving Permission Denied error. I replaced with as below and it worked,

with open('filename.ext', 'wb') as file_output: file_output.write(file.content) loader = Loader('filename.ext')
