I am working on a project on a Raspberry Pi where I need to create a security camera system. I have 3 python files for this project one for live streaming, another one for motion detection and finally the last for activating the motion detection file from an android application. I am trying to make the live stream and motion detection file use the same camera. In the live stream file(live.py) I have imported a socketserver module to make the live stream, which works well when run. However, when I am trying to import the live.py file into the motion detection file(motion.py), I am getting an Import Error. The error is shown below:
Traceback (most recent call last):
File "motion.py", line 10, in <module>
import live.py
File "/home/pi/codes/live.py", line 7, in <module>
import socketserver
ImportError:No module named socketserver
I am very confused, I don't know what this error is. Any help would be very appreciated. Thank you.
it looks like live.py is in a subdirectory. Python cannot access python files that are NOT in python packages. So, you need to ensure that all the folders that live.py is in are PYTHON PACKAGES.
To make a folder into a python package simply add a init.py file to each folder (you do not need to write any code in this file)
Then when you import live.py the import will look like this
from root.folder_name import live

I'm attempting to figure out the mechanics of running Python scripts in Power BI for Reasons and I've hit a snag. I was running through the steps in this somewhat basic tutorial and I came to the section in which I am supposed to paste the script into they Python Script screen, which is Step 3 of the 'Run the Script and Import Data' section.
When I followed the steps, which are essentially to paste the example script into the window and hit Okay, I got this 'helpful' error:
`

I have verified that the matplotlib and pandas packages were installed via pip list, os doesn't show up, which surprised me but I know it's part of the standard library so I'm not stressing about it unless someone thinks I should. Is anyone an expert in this? Is there a better way? Am I doomed to scream into the Power BI void for all eternity?
The somewhat basic tutorial is based on using standard python from python.org. However, you are using the Anaconda distribution, which basically requires the environment to be activated before any modules - especially pandas' C-library - can be accessed.
You can achieve that in the cmd shell by running
conda activate
C:\Users\my.username\AppData\Local\Microsoft\WindowsApps\PBIDesktopStore.exe
which assumes that you are using the Power BI Desktop version from the Microsoft store.
So I have a hobby I like to do where I program automated systems that upload things to social media with no human input (and make a little side cash). But anyways, I've been trying to crack YouTube recently. YouTube has their own little way to upload videos automatically, but they watch over it INTENSELY. So, I found a work around using youtube_uploader_selenium, a cool little github project that allows you to upload as many videos as you want to YouTube through selenium firefox.
I know if I can get it to work, I can have a fully automated YouTube channel, however one single, important line of code doesn't work properly.
So the module is accessed via an import command in my main script
from youtube_uploader_selenium import YouTubeUploader
I was able to get that working, however when I did I got an error within the module from this line of code saying that selenium_firefox wasn't a valid pip/module.
from selenium_firefox.firefox import Firefox, By, Keys
So, I did some digging and found a PipInstaller script I could use.
import subprocess
import sys
py_exec = sys.executable
# ensure pip is installed & update
subprocess.call([str(py_exec), "-m", "ensurepip", "--user"])
# install dependencies using pip
subprocess.call([str(py_exec),"-m", "pip", "install", "selenium_firefox"])
That had some odd error involving Rust and the Cryptography pip so I decided to take a different approach. I tracked down the selenium_firefox github then downloaded the module from there. In the script I added a line which made it look for the module selenium_firefox in a certain folder where it was downloaded.
from typing import DefaultDict, Optional
from selenium_firefox.firefox import Firefox, By, Keys # problem code
from collections import defaultdict
import json
import time
from .Constant import *
from pathlib import Path
import logging
import platform
selenium_firefox.path.append(
"C:\\Program Files\\Blender Foundation\\Blender2.92\\2.92\\python\\PythonModules\\modules\\")
That <kinda???> worked. This is the error I currently have,
Traceback (most recent call last):
File "C:\Users\CLASSIFIED\Downloads\ASAS\zxxxs.blend\CLASSIFIEDSCRIPTNAME", line 5, in <module>
File "C:\Program Files\Blender Foundation\Blender 2.92\2.92\python\PythonModules\modules\youtube_uploader_selenium\__init__.py", line 2, in <module>

from .firefox import Firefox
ModuleNotFoundError: No module named 'selenium_firefox.firefox'
Error: Python script failed, check the message in the system console
I don't know where to go from here. The module within the module within the module has errored. This is what the script for the script that's currently producing this error.
from .firefox import Firefox
from .models import *
from .firefox_addons import *
from selenium_browser import *
I know proper python importing has been asked time and time again, but I'm not sure how to taclke this situation.
I'm developing a few scripts that depend on each other to work. I am also making a streamlit app to launch the main scipts. This is the folder structure:
gui.py
pages/page1.py
pages/page2.py
database/mongo_queries.py
database/mongo_methods.py
database/mongo_objects.py
mongo_queries imports methods and objects straight up, as they are in the same folder.
import mongo_methods as mm
I'm running streamlit run from the root folder (this may get migrated to a docker
later). gui.py and all pages require importing from ./ using database.mongo_methods.
import database.mongo_queries as mq
So I'm getting the following import erorrs when trying to use one of the functions from the script
ModuleNotFoundError: No module named 'mongo_objects'
File "pages/1_database.py", line 3, in <module>
import database.mongo_queries as mq
File "{full_path}/database/mongo_queries.py", line 1, in <module>
from database import mongo_methods
File "{full_path}/database/mongo_methods.py", line 1, in <module>
from mongo_objects import Something
Both the gui and the scripts are constantly being updated so I can't keep repackaging and reinstalling the code. What's the proper way of solving this?
I am working on a project involving the popular aiortc/aioquic github package. Located at src/aioquic/buffer.py there is an import statement:
from ._buffer import Buffer, BufferReadError, BufferWriteError # noqa
This line is meant to import a C/stub module _buffer.c / _buffer.pyi . When used from the root directory to run examples found in the examples directory this import line will work, but when trying to run in a Docker container from the same directory this import fails and when importing from the /src directory the import fails. I have tried reading several other questions on python relative imports but none seem to make sense to me.
To reproduce the issue:
open python in the src directory
from aioquic import about (works)
from aioquic import buffer (fail)
from aioquic import buffer
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/aioquic/src/aioquic/buffer.py", line 1, in <module>
from ._buffer import Buffer, BufferReadError, BufferWriteError # noqa
ModuleNotFoundError: No module named 'aioquic._buffer'
I don't understand why the examples http3_client and http3_server work but when trying to import it directly it fails. I thought I understood roughly how to use python imports but apparently not. What would cause the same line to work when running from one directoy but fail when running from another directory? Is it something magical with the PYTHONPATH? I'm hoping someone smarter than I am can explain why this is failing.
[EDIT and most importantly how to fix this so the import will work nomatter where the user runs python from. I have tried several different combinations but none seem to work.]
Thanks in advance.
I figured out what was wrong.
The stub/C module had to be built into a .pyd file before it could imported. This was done by
pip install -e .
on the parent directory
Is it something magical with the PYTHONPATH?
Yes.
Typically . dot (current working directory) will appear
in that exported env var,
so where you started matters.
Take care to ensure you're using the same env var setting,
and the same pwd,
during both the interactive and the Docker runs.
I want to make a file that is consisted of 3 python programs.
but, when I want to access one of the there files from one of them, it cant find the folder.
I made a init python file in it so python can recognize it as a module
my folder struct:
dlgo/
__init__.py
goboard_slow.py
gotypes.py
my goboard_slow:
from dlgo.gotypes import player
error:
Traceback (most recent call last):
File "C:\Users\asus\Desktop\dlgo\goboard_slow.py", line 2, in <module>
from dlgo.gotypes import player
ImportError: No module named 'dlgo'
Access as below:
from dlgo.gotypes import players
See here more info on "Guido's decision" on imports in python 3 and complete example on how to import in python 3.
maybe try from (filename) import (functionname)
Tl;dr:
from gotypes.py import player
when you specify path to a file, interpreter starts looking for it inside same folder, unless you give it path from main dirrectory like '/' or 'C:\'
You can import a py file with the following statement:
# Other import
import os
import sys
if './dlgo' not in sys.path:
sys.path.insert(0, './dlgo')
from dlgo.gotypes import player
NOTE:
For IDE like PyCharm, you can specify the import path using the Project Structure setting tab (CTRL+ALT+S)
