Package it as an exe using pyinstaller, and starting the exe will continuously create processes until the memory is exhausted

[wesley15151409100-code]

Question

issue：
I use the simplest example, which is packaged using pyinstaller. The packaged exe executable file, when clicked to run, will continuously create processes until the memory runs out and the machine freezes

environment：
windows 10
python 3.8
charts latest version

Pyinstaller command：
pyinstaller -F -p D:\python_project\tradingview_backtest\Lib\site-packages -w test.py

Code example

code demo：
import pandas as pd
from lightweight_charts import Chart

if __name__ == '__main__':
    chart = Chart()

    df = pd.read_csv('ohlcv.csv')
    chart.set(df)

    chart.show(block=True)

I have no memory issues, but I am also not able to show the demo application.

with the following error.

JavaScript Error 1: {'name': 'ReferenceError', 'stack': 'ReferenceError: Lib is not defined\n    at eval (eval at <anonymous> (:4:29), <anonymous>:3:23)\n    at <anonymous>:4:29', 'message': 'Lib is not defined'}

I guess the HTML and JS files need to be included into the binary?

how did you package it？

I was able to pack the basic test application using pyinstaller. Here is what I did.

python -m site gives you something like

sys.path = [
    '/home/user/test',
    '/usr/lib/python312.zip',
    '/usr/lib/python3.12',
    '/usr/lib/python3.12/lib-dynload',
    '/home/user/test/.venv/lib/python3.12/site-packages',
]
USER_BASE: '/home/user/.local' (exists)
USER_SITE: '/home/user/.local/lib/python3.12/site-packages' (doesn't exist)
ENABLE_USER_SITE: False

Then pack the application using

pyinstaller --onefile basicTest.py --add-data "/home/user/test/.venv/lib/python3.12/site-packages/lightweight_charts/js:lightweight_charts/js"

This includes the static HTML and JS files as data to the binary.

The OHLCV file needs to be in the same folder as the binary (copy into ./dist) to run the application.

Next step to actually gain some performance: Build the application using nuitka.

Using the same method still produces an error, similar to the memory issue I raised

import pandas as pd
from lightweight_charts import Chart
import logging
import os

配置日志

logging.basicConfig(
level=logging.DEBUG,
format='%(asctime)s - %(levelname)s - %(message)s',
handlers=[
logging.FileHandler("log.log"),
logging.StreamHandler()
]
)
logging.info(f"开始")

if name == 'main':
logging.info(f"main")
chart = Chart(debug=True)
logging.info(f"创建chart")
df = pd.read_csv("bar_data/ohlcv.csv")
logging.info(f"读取文件：{df}")
chart.set(df)
logging.info(f"chartset")
chart.show(block=True)
logging.info(f"chartshow")
logging.info(f"end")

The task manager shows that the packaged exe program keeps running processes until the memory runs out
