Question

I am importing a class Chart() whose object I am creating in my code Someone raised a github issue with similar issue, there @louisnw01 replied that You must encapsulate the Chart object within an if name == 'main' block.

Now I'll explain what my code is doing Inside the if name == 'main' block, I am invoking an async function using asyncio.run(main()) Now Inside the main, I am awaiting another async function called processMessage which is written in another file, and inside that processMessage Function I am invoking another function called createChart which is again in another file which is creating the Chart object and it returns the screenshot in bytes array.

I am not sure what I am doing wrong I even tried to delete the chart object which I created from Chart class This is where I am creating Chart object I am invoking this function through another function which is called insides if name=='main' block, I am not sure how to fix it

import pandas as pd
from dtos.webhookDtos import SmaCreateChart
import gc

def createChart(data: pd.DataFrame, sma: SmaCreateChart = None):
    chart = Chart()
    if sma:
        line = chart.create_line(name=f'SMA {sma.period}')
        line.set(sma.data)
    chart.set(data)
    chart.show(block=False)
    img = chart.screenshot()
    chart.exit()
    del chart
    gc.collect()
    return img
