which python version are you using?

How to prevent users from connecting nodes that aren't with the same type,
for example, prevent user to connect a str output to an int input?

My development environment is:

• Windows 10
• python 3.7.9
• dash 2.0

When I run the basic usage example from https://github.com/idling-mind/flowfunc#readme:

C:\Users\chenxiaowang\dash-apps\flowfunc-master\learn>ppython basic_usage.py
Traceback (most recent call last):
File "basic_usage.py", line 5, in
from flowfunc.config import Config
File "C:\Panda3D-1.10.10-x64\python\lib\site-packages\flowfunc\config.py", line 5, in
from typing import Any, Callable, List, Optional, Union, get_args, get_origin
ImportError: cannot import name 'get_args' from 'typing' (C:\Panda3D-1.10.10-x64\python\lib\typing.py)

I fixed it:

• pip install typing_extensions
• modify flowfunc\config.py

Modify flowfunc\config.py as the flowing:

• delete one line:

from typing import Any, Callable, List, Optional, Union, get_args, get_origin

• add these lines:

from typing import Any, Callable, List, Optional, Union
try:
    from typing import  get_args
except ImportError:
    from typing_extensions import  get_args
try:
    from typing import  get_args
except ImportError:
    from typing_extensions import  get_args

I aslo modify basic uasage exmaple code:

@app.callback(
    Output("output", "children"),
    Input("btn_run", "n_clicks"),
    State("nodeeditor", "nodes"),
    #prevent_initial_callbacks=False
)
def run_nodes(nclicks: int, output_nodes: Dict[str, OutNode]):
    """Run the node layout"""
    # The result is a dictionary of OutNode objects
    # check output_nodes is None 
    if output_nodes is None:
        return []
    result = runner.run(output_nodes)
    output = []
    for node in result.values():
        # node.result contains the result of the node
        output.append(
            html.Div([html.H1(f"{node.type}: {node.id}"), html.P(str(node.result))])
        )
    return output

if __name__ == "__main__":
    # AttributeError: 'Dash' object has no attribute 'run'
    ##app.run() 
   app.run_server(debug = True, host = '192.168.0.114', use_reloader=False, dev_tools_hot_reload=False)

The basic usage example has run successfully on my development environment. VERY COOL!

I do not have git installed on Windows 10. An alternative that avoids git is to install from a zip. I install flowfunc successfully:

1. download code zip, flowfunc-master.zip placed in my dowload dir
2. pip install /Users/chenxiaowang/Downloads/flowfunc-master.zip

Is it possible to have upload and download nodes for different file types like images, audio etc?

I know there were upload and download buttons in the sample project, but I wanted to use it as a node in the graph instead of downloading/uploading a graph.

Really awesome work! Thank you!

I saw that you don't provide a license (yet). Are there plans to add one? Otherwise, it might be problematic for some folks (like me 😅 ) to use your package.

flowfunc requires pydantic>=1.9 ( pydantic-1.10.2 installed) is incompatible with existing packages of my app:

• thinc 8.0.15 requires pydantic!=1.8,!=1.8.1,<1.9.0,>=1.7.4, but you have pydantic 1.10.2 which is incompatible.
• spacy 3.2.4 requires pydantic!=1.8,!=1.8.1,<1.9.0,>=1.7.4, but you have pydantic 1.10.2 which is incompatible.

I have to solve these dependency conflicts.

After all, I have successfully installed flowfunc-0.0.1 and pydantic-1.10.2.

Next, run the basic usage example.

I want to make a node with a sting input and a dropdown to choose a value.
how should i go about it?

def function1(name:str, drop_downlist)->str:
   something = process(name, choice)
   return something
