I want to monitor if the file has been changed through using watchdog in Python, however, when I test, the terminal give me a warning,
"C:\Python27\lib\site-packages\watchdog\observers\__init__.py:89:UserWarning:Failed to import read_directory_changes. Fall back to polling.warning.warn("Failed to import read_directory_changes. Fall back to polling")"
I've installed pip to install watchdog, however, I still don't know how this problem occur.
here is the test code:
# coding=utf-8
import sys
import time
import logging
import urllib
import urllib2
import os
# import MySQLdb
from watchdog.observers import Observer
from watchdog.events import FileSystemEventHandler
print "hello"

I created a GPS Script on my raspberry pi. It imports a couple of modules.
When I connect to the RPI via Visual Studio Code SSH, and execute: sudo python3 gpsd.py, the script starts. But when I try the exact same command on the local machine, I get a ModuleNotFound on the GPS and Alive_progress modules. Does anyone know what could be going wrong here?
from gps import *
from time import *
import time
import threading
import sys
from alive_progress import alive_bar
from datetime import datetime, date
import csv
from keep_alive import keep_alive
from gpiozero import CPUTemperature
import subprocess
import sys
You must have all these modules installed in your local I think
I'm trying to run this python project on my linux machine. I did setup everything according to the requirement but when I try to run the project with the ./generate.sh executable file I got the following error.
Import Error: No module name tqdm found.
Here are the imports exists in file.
import os.path as path
import ast
from glob import glob
import signal
import imp
import logging
import time
import numpy as np
import socket
import tqdm
import sys
import click
import tensorflow as tf
from tensorflow.python.client import timeline
I check with pip3 show tqdm command it shows me the package detail. I also try to uninstall and install again the project but got no luck.
If i remove the tqdm import from the file then it shows me this error.
File "./run.py", line 16, in <module>
import click
ImportError: No module named click
Can someone guide me what I'm doing wrong here?
it seems you are importing it wrong, from tqdm docs:
from tqdm import tqdm
I've checked it for both python2 and 3 and this is the way to use it.
The project you are trying to use at least 3 years old, so maybe things have changed since then, so if it wont work for you even with proper import statement you can simply remove it.
Every loop working with tqdm will work without it as well.
For example:
from tqdm import tqdm
for i in tqdm(range(10000)):
pass
is the same as:
for i in range(10000)):
pass
I am trying to implement the code in https://github.com/kexinyi/ns-vqa.
However, when I try the command, python tools/preprocess_questions.py \ ... in the section of "Getting started". I see a message No module named 'utils.programs'.
Then I install utils and which makes import utils work, but import utils.programs does not work.
Does anyone have any idea to solve it?
import os
import argparse
import json
import h5py
import numpy as np
import utils.programs as program_utils # this one cannot be imported
import utils.preprocess as preprocess_utils
import utils.utils as utils
Solution:
Add the below lines at the beginning of preprocess_questions.py file.
import sys
sys.path.insert(0, "..")
This should solve your problem.
Explanation:
It is failing because preprocess_questions.py don't know about the path of utils.programs to import. With the above lines added to the path using .., the required file will be imported.
For more on this refer how importing works in python.
I got this code in Python 2.7:
#!/usr/bin/env python
# -*- coding:utf-8 -*-
import logging

from GUI import *
from arduinoSerial import *
from bs4 import BeautifulSoup
from ledDisplay import *
from timeout import timeout
When I run it an error occurs:
from GUI import *
ImportError: No module named GUI
I try to install GUI, but I couldnt:
Try to run this command from the system terminal. Make sure that you use the correct version of 'pip' installed for your Python interpreter located at '/home/in/PycharmProjects/untitled/venv/bin/python
Did I made somehting bad? Could someone help me?
Is there a module called "GUI" that you're trying to import?
Tkinter is the standard Python GUI framework. Maybe you're thinking of that, in which case you would need to use from tkinter import *.
I've two Python scripts as given below
inner.py
#!/usr/bin/python
import os
import datetime
# <---- Some Code--->
main.py
#!/usr/bin/python
import os
import datetime
# <---- Some Code--->
subprocess.call(["/usr/bin/python",inner.py])
The problem is when the inner.py script is called from the main.py script it doesn't import any modules. For example it says
ImportError: No module named os
But when the script is executed standalone it works fine. Please help
The following works perfectly fine for me, and it's modified because some of your code seemed a little incomplete.
inner.py
#!/usr/bin/python
import os
import datetime
print os.getcwd()
main.py
#!/usr/bin/python
import os
import datetime
import subprocess
import sys
# <---- Some Code--->
subprocess.call([sys.executable, "inner.py"])
