This looks like langroid is not being recognized at all in your environment.

Please following the exact install instructions in the README of the langroid-examples repo: https://github.com/langroid/langroid-examples

If it still doesn't work, let me know the exact steps you took to install langroid.

from langroid.

I followed the instructions and the script in the examples folder runs fine, but when I make another file let's say "lagroid.py" and copy the content of script "doc-chat-2.py" into that and run it then am getting the modulenotfound error. why is that?

from langroid.

In that case there may have been an issue with how the contents were copied. For example if you simply rename the script to new.py and run new.py it should of course work.

Thank you for your help. Apparently, now I am facing a connection error to OpenAI. I am running the following script:

(1) Get the lease document

import requests
file_url = "https://raw.githubusercontent.com/langroid/langroid-examples/main/examples/docqa/lease.txt"
response = requests.get(file_url)
with open('lease.txt', 'wb') as file:
file.write(response.content)

verify

#with open('lease.txt', 'r') as file:

print(file.read())

from langroid.agent.special import DocChatAgent, DocChatAgentConfig
from langroid.vector_store.lancedb import LanceDBConfig
from langroid.embedding_models.models import OpenAIEmbeddingsConfig
from langroid.embedding_models.models import SentenceTransformerEmbeddingsConfig
from langroid.parsing.parser import ParsingConfig

oai_embed_config = OpenAIEmbeddingsConfig(
model_type="openai",
model_name="text-embedding-ada-002",
dims=1536,
)

(2) Configure DocChatAgent

cfg = DocChatAgentConfig(
name="RAG",
parsing=ParsingConfig(
chunk_size=100,
overlap=20,
n_similar_docs=4,
),
show_stats=False,
cross_encoder_reranking_model="",
llm=llm_cfg,
vecdb=LanceDBConfig(
embedding=oai_embed_config,
collection_name="lease",
replace_collection=True,
),
doc_paths=["lease.txt"]
)

(3) Create DocChatAgent, interact with it

rag_agent = DocChatAgent(cfg)
response = rag_agent.llm_response("What is the start date of the lease?")
assert "2013" in response.content

And the error I got is this and keeps going on:

I have enough balance in my openai account and generated new keys but it does not seem to work and stuck at making connection.

Before trying this example, can you run this and see if it works:

import langroid as lr
import langroid.language_models as lm

llm_config = lm.OpenAIGPTConfig()
agent_config = lr.ChatAgentConfig(
    llm=llm_config,
    system_message="You are a helpful assistant, help me with some questions"
)

agent = lr.ChatAgent(agent_config)
task = lr.Task(agent, interactive=True)

task.run()

from langroid.

This works!

This means your OpenAI API Key setup is all good.

Next try this simple doc-chat script :

python3 examples/docqa/rag-local-simple.py

Also see inside the script for other instructions.

I'm suggesting the above scripts since these are the simpler ones to try before the more complex doc-chat-2.py

Tried it, and the connection error persists.

Hello,
With the recent March 2024 updates, The code I have been running is throwing me this error:

TypeError Traceback (most recent call last)

----> 1 from langroid.language_models.openai_gpt import (

TypeError: Tuple[t0, t1, ...]: each t must be a type. Got <module 'PIL.Image' from '/usr/local/lib/python3.10/dist-packages/PIL/Image.py'>.

The following is the code I am using:

from langroid.language_models.openai_gpt import (
OpenAIChatModel, OpenAIGPT, OpenAIGPTConfig
)

It was working fine before, but after the recent updates, it is not.

Your error trace shows python3.10. Langroid requires 3.11 as it says in the README.
