The following piece of code was working fine for a year, of late it intermittently started failing with following error, wonder if any OS or hardware change is causing this
import subprocess
def bash_command(cmd):
process = subprocess.Popen(cmd, shell=True, executable="/bin/bash")
process.wait()
bash_command("bash myscript.sh")
The error message is:
Traceback (most recent call last): File

I am trying to schedule my script on pythonanywhere with a beginner account.
Here is my code
class SeeTicket(webdriver.Chrome):
def __init__(self ,driver_path='/home/saifbyte/seetickets/chromedriver.exe', teardown = False):
options = webdriver.ChromeOptions()
options.add_experimental_option("detach", True)
options.add_experimental_option( 'excludeSwitches' , ['enable-logging'])
options = options
self.driver_path = driver_path
self.teardown = teardown
super(SeeTicket , self).__init__(options = options , executable_path=self.driver_path)
self.maximize_window()
but when I am scheduling this task , i get the following error:
selenium.common.exceptions.WebDriverException: Message: 'chromedriver.exe' executable may have wrong permissions. Please see https://sites.google.com/a/chromium.org/chromedriver/home
whole traceback:

My executable path is correct but still getting error.
Alternatively are there any good alternative to pythonanywhere.
Thanks
From the Traceback I observe a linux styled path:
/home/saifbyte/seetickets/...
Presumably an non windows system.
Solution
You need to drop the extension of the ChromeDriver binary executable. Your effective line of code will be:
def __init__(self ,driver_path='/home/saifbyte/seetickets/chromedriver', teardown = False):
#Function to click a button on DocDroid website
def sendpdf():
import selenium
driver=webdriver.Chrome()
driver.get('https://www.docdroid.net/')
upload_box=driver.find_element_by_id('select')
upload_box.click()
sendpdf()
if I add 'from selenium import webdriver' I get the following error:

I'm for some reason getting the following error:

You need to add chromedriver in your system PATH, you can download it from here
I'm trying to run a video processing code on NVIDIA TX2 using moviepy. The code is:
clip = VideoFileClip(video_file)
video_clip = clip.fl_image(process_vid)
video_clip.write_videofile(output_vid2)
I get the error in the first line. The full error is:

I even used the refernce of this but nothing seems to work.
Any suggestions?
completeProcess = subprocess.run("la")
This is my code to run commands via python, and it raise this error:
Traceback (most recent call last):
File "script_senior.py", line 171, in <module>
completeProcess = subprocess.run("la") # doesn't capture output
File "/usr/lib/python3.5/subprocess.py", line 693, in run
with Popen(*popenargs, **kwargs) as process:
File "/usr/lib/python3.5/subprocess.py", line 947, in __init__
restore_signals, start_new_session)
File "/usr/lib/python3.5/subprocess.py", line 1551, in _execute_child
raise child_exception_type(errno_num, err_msg)
FileNotFoundError: [Errno 2] No such file or directory: 'la'
My OS is ubuntu, and when enter "la" in terminal, it will list files(include hidden files) in current working directory. and "ll" cmd will list file details. but I can't use them in python's subprocess api
How can I achieve this function? Is there any common api to run commands or just the python didn't recognize "la"
la is an alias for 'ls -A'. That comes as a default shell alias in systems like Ubuntu. If you wanna run it just use:
completeProcess = subprocess.run(["ls","-A"])
and if you are looking for the stdout you can use something like:
completeProcess = subprocess.run(["ls","-A"] , stdout=subprocess.PIPE)
print(completeProcess.stdout.decode())
I am trying to call a function using subprocess.Popen as:
proc = subprocess.Popen(["/usr/local/bin/qstat", "-u", "rudrab"],stdout=subprocess.PIPE)
numjobs = proc.stdout.read()
which is giving error:
Traceback (most recent call last):
File "genpos.py", line 159, in <module>
proc = subprocess.Popen(["/usr/local/bin/qstat", "-u", "rudrab"],stdout=subprocess.PIPE)

raise child_exception_type(errno_num, err_msg)
FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/bin/qstat'
but qstat is in my path:
which qstat
/usr/local/bin/qstat
what I am doing wrong here?
