I am new to streamlit and trying to navigate this error. I have tried adding keys to the components that require them, but I suspect that the issue is a little deeper. I have created a simple chatbot that calls OpenAI. This is working fine - I can send multiple queries and get the responses with no problem.
This code works fine:
prompt = st.text_input("Prompt", placeholder="Enter prompt here..", key="user_input")
with st.sidebar:
with st.spinner("Loading..."):
time.sleep(1)
st.success("Done!")
if "user_prompt_history" not in st.session_state:
st.session_state["user_prompt_history"] = []
if "chat_answers_history" not in st.session_state:
st.session_state["chat_answers_history"] = []
if "chat_history" not in st.session_state:
st.session_state["chat_history"] = []
def create_sources_string(source_urls: Set[str]) -> str:
if not source_urls:
return ""
sources_list = list(source_urls)
sources_list.sort()
sources_string = "sources:\n"
for i, source in enumerate(sources_list):
sources_string += f"{i+1}. {source}\n"
return sources_string
if prompt:
with st.spinner("Generating response.."):
generated_response = run_llm(
query=prompt, chat_history=st.session_state["chat_history"]
)
sources = set(
[doc.metadata["source"] for doc in generated_response["source_documents"]]
)
formatted_response = (
f"{generated_response['answer']} \n\n {create_sources_string(sources)}"
)
st.session_state["user_prompt_history"].append(prompt)
st.session_state["chat_answers_history"].append(formatted_response)
st.session_state["chat_history"].append((prompt, generated_response["answer"]))
if st.session_state["chat_answers_history"]:
for generated_response, user_query in zip(
st.session_state["chat_answers_history"],
st.session_state["user_prompt_history"],
):
message(user_query, is_user=True)
message(generated_response)
the problems start when I add in the button to clear the chat. Again, I can correspond with OpenAI just fine. When I click the button, I get the error. One thing to note: I see the chat box area attempt to refresh - could that be part of the issue? The last line in the error seems to indicate that.
The updated code (I added st.sidebar button and corresponding function)):
prompt = st.text_input("Prompt", placeholder="Enter prompt here..", key="user_input")
**def reset_conversation():**
** st.session_state.conversation = [] # original value: None**
** st.session_state.chat_history = [] # original value: None**
** st.session_state.messages = []**
with st.sidebar:
with st.spinner("Loading..."):
time.sleep(1)
st.success("Done!")
st.sidebar.button('New Chat', on_click=reset_conversation, key="button1")
if "user_prompt_history" not in st.session_state:
st.session_state["user_prompt_history"] = []
if "chat_answers_history" not in st.session_state:
st.session_state["chat_answers_history"] = []
if "chat_history" not in st.session_state:
st.session_state["chat_history"] = []
def create_sources_string(source_urls: Set[str]) -> str:
if not source_urls:
return ""
sources_list = list(source_urls)
sources_list.sort()
sources_string = "sources:\n"
for i, source in enumerate(sources_list):
sources_string += f"{i+1}. {source}\n"
return sources_string
if prompt:
with st.spinner("Generating response.."):
generated_response = run_llm(
query=prompt, chat_history=st.session_state["chat_history"]
)
sources = set(
[doc.metadata["source"] for doc in generated_response["source_documents"]]
)
formatted_response = (
f"{generated_response['answer']} \n\n {create_sources_string(sources)}"
)
st.session_state["user_prompt_history"].append(prompt)
st.session_state["chat_answers_history"].append(formatted_response)
st.session_state["chat_history"].append((prompt, generated_response["answer"]))
if st.session_state["chat_answers_history"]:
for generated_response, user_query in zip(
st.session_state["chat_answers_history"],
st.session_state["user_prompt_history"],
):
message(user_query, is_user=True)
message(generated_response)
The last part of the error references the last couple of lines in the code. Is that a clue?
