BUG- Dataframe not refreshing properly

[FlorianJacta]

Description The behavior between a local run and a run done with Docker and Gevent is different. In this example, the table is not updated properly. Refreshing the page solves the refresh of the page. invoke_long_callback is used so the code should work.

How to reproduce app.py

from taipy import Gui
import pandas as pd
import time
from taipy.gui import(
    Markdown,
    notify,
    get_state_id,
    invoke_long_callback,
)

calculate_label = "Calc"
calculate_label_active = True
df = pd.DataFrame({"V": [21], "W": [22], "X": [23],"Y": [24],"Z": [25]})

def calculate_action(state):
    state.calculate_label = "0"
    state.df = pd.DataFrame({"V": [21], "W": [22], "X": [23],"Y": [24],"Z": [25]})

    invoke_long_callback(state,
        user_function=do_calculate,
        user_function_args=[get_state_id(state)],
        user_status_function=get_status_calculate,
        period=1000)

def get_status_calculate(state, status, result):
    if isinstance(status, bool):
        if status:
            notify(state, "success", "Heavy set function finished!")
            state.df = result

            state.calculate_label = "Calc"
        else:
            notify(state, "error", "Something went wrong")

    else:
        state.calculate_label = str(int(state.calculate_label)+1)

def do_calculate(state_id):
    time.sleep(15)
    df_old = pd.DataFrame({"A": [1], "B": [2], "C": [3], "D": [4], "E": [5]})
    df_new = pd.DataFrame({"A": [12], "B": [14], "C": [16], "D": [18], "E": [20]})
    try:
        df_result = df_new.subtract(df_old, fill_value=0)
    except Exception as ex:
        raise ex

    return df_result

calc_md = Markdown(
    """
<|{calculate_label}|button|on_action=calculate_action|active={calculate_label_active}|>

<|{df}|table|>
"""
)

pages = {"Calculate": calc_md}

if __name__=="__main__":
    port = 8080
    Gui(pages=pages).run(title="Test", dark_mode=True, port=port, host="0.0.0.0")

    app = Gui(pages=pages).run(title="Test", dark_mode=True, run_server=False)

Expected behavior

The behavior should be the same.

Runtime environment Please specify relevant indications.

• Taipy version (or branch name): 3.0
• Docker with gevendt and local run with windows

Acceptance Criteria

• [ ] Ensure new code is unit tested, and check code coverage is at least 90%
• [ ] Create related issue in taipy-doc for documentation and Release Notes if relevant

I tried to replicate the issue on both local and docker. The provided code does not work on both environment. I suspect that this is not an environment issue but a dataframe reload issue.

Related to #1054

[FredLL-Avaiga]

not related to #1054 (which is a regression that appeared after 3.1)

[FredLL-Avaiga]

@FlorianJacta can you confirm that your issue is still present in develop ?

[FlorianJacta]

When I run the code in the develop version locally, it works.

[FlorianJacta]

I tested it with Docker on 3.1, and it doesn't work. I have the same issue

@FlorianJacta I did tested it again with Fred using the develop branch. Please help me retest it on your side. I did change 2 things.

• the table should have the rebuild tag --> <|{df}|table|rebuild|>
• the requirements.txt file should have taipy rebuild branch entry (alias of develop branch with the frontend side already built)--> taipy @ git+https://github.com/Avaiga/taipy.git@prebuild#egg=taipy

[FlorianJacta]

I tried but there are problems with Taipy dependencies. I will try again when this is fixed

taipy-1  |   File "/home/userr/.local/lib/python3.9/site-packages/taipy/config/_config_comparator/_config_comparator.py", line 16, in <module>
taipy-1  |     from deepdiff import DeepDiff
taipy-1  | ModuleNotFoundError: No module named 'deepdiff'

It seems to be related to https://github.com/Avaiga/taipy/issues/1668

[dinhlongviolin1]

@FlorianJacta You can try again with the commit on Taipy.

pip install "taipy@git+https://git@github.com/Avaiga/taipy.git@b126c80726e814aff219ecd8456dd4378f36b270"

[dinhlongviolin1]

equivalent to this inside requirements.txt taipy @ git+https://github.com/Avaiga/taipy.git@b126c80726e814aff219ecd8456dd4378f36b270#egg=taipy

[FlorianJacta]

How did you change the Dockerfile?

The installation of Taipy was not successful as I don't have node/npm installed in the dockerfile. I have tried to install it but this leads to another error.
