Hi @sargupta , I can't repro the issue. Can I know what extension version you used? If it was not the latest version. Can you try to update to the latest and then have a try? If you still encounter the same issue, can you please share the content of the flow.dag.yaml file and the content of the .promptflow/flow.tools.json file?

By the way, there is a known issue with python 3.12. If you use python 3.12, you may need to downgrade to 3.11.

Hi @naiyunzhang

  • pf version: 1.5.0
  • python version: 3.11.5 (previously tried 3.12.1)

Tried using python 3.11 however it didn't solve the issue.
Here is the content of flow.dag.yaml file:

name: Template Chat Flow
environment:
  python_requirements_txt: requirements.txt
inputs:
  chat_history:
    type: list
  question:
    type: string
    is_chat_input: true
outputs:
  answer:
    type: string
    reference: ${parent.output}
    is_chat_output: true
nodes:
- name: parent
  type: llm
  source:
    type: code
    path: parent.jinja2
  inputs:
    deployment_name: gpt-35-turbo
    max_tokens: 256
    temperature: 0.7
    chat_history: ${inputs.chat_history}
    question: ${inputs.question}
  provider: AzureOpenAI
  connection: azure_open_ai_connection
  api: chat
- name: parent_variant_gpt4
  type: llm
  source:
    type: code
    path: parent_variant_gpt4.jinja2
  inputs:
    deployment_name: gpt-4
    max_tokens: 256
    temperature: 0.7
    chat_history: ${inputs.chat_history}
    question: ${inputs.question}
  provider: AzureOpenAI
  connection: azure_open_ai_connection_gpt4
  api: chat

However, there is no such file as .promptflow/flow.tools.json.
List of files you can find in the above screenshot.

@sargupta I mean the prompt flow vscode extension version. You can find your extension version here:

The .promptflow/flow.tools.json file should be located in evaluation_dev/exp_eval_dev_flow_01/.promptflow/flow.tools.json.

And, have you updated your flow.dag.yaml file from the time this issue occurred? It seems that there is not a variant on the node parent named variant_1 in this flow.dag.yaml file.

@sargupta The version v1.0.7 is old. There was a bug in some old versions and it has been fixed in newer versions. I believe an update to the newest version will fix the issue you encountered. Please have a try. Much thanks.
