From what I see you have an error in line 7 as it's pointed out in the traceback.
In the line of code you define your path you're trying to use an absolute path.
PATH ="/Users/kaikeichan/Desktop/python_webpage/chromedriver"
The problem in here may be that you are not writing the right path to the chromedriver file. Your path should have a C: before user (that is if you have your project stored in your computer and not an external hard drive or something similar) like this:
PATH ="C:/Users/kaikeichan/Desktop/python_webpage/chromedriver"
Another thing you could try is adding a ".exe" in the end of chromdriver as it is a .exe file and you should specify that.
PATH ="C:/Users/kaikeichan/Desktop/python_webpage/chromedriver.exe"
I really hope this helps and I would suggest you try to use a relative path because it could be simpler to you. If your ".py" python file is in the same folder your chromdriver file is allocated then you could just define the path as "chromedriver.exe" and that would be an effective use of a relative path.

ValueError: Could not get version for Chrome with this command: reg query

I am using selenium with python and have downloaded the chromedriver for my windows computer from this site. After downloading the zip file, I unpacked the zip file to my downloads folder. Then I add the path to the the Environment Variable "Path".
I want to get information from the site, but when I run code, I get this error and comletely don't understand what is it about.

Sorry, I am very new to Python, but if somebody could help, I'll be very pleased and thankful.

I solved problem. I don't understand why I've hadn't think of this solution before - all you need to do is to write the path of your chromedriver (only if you have a correct version)
browser = webdriver.Chrome('path')

important to know for people searching for the same error and ending here. chrome needs to have started at least once to generate the reg key in windows.

I suspect that you are using a selenium web-driver that is not matching your chrome driver version.
you can update your chrome using the following link:

selenium python problem with loading page driver.get('http://page.com/') open empty window

You need to provide geckodriver path not firefox. Check your firefox browser version and you can download compatible geckodriver from Here
browser = webdriver.Firefox(executable_path="path of geckodriver")
Sample code
browser = webdriver.Firefox(executable_path="/Users/username/Location/geckodriver")
browser.get("https://google.com")

You can add the path to your webdriver in the PATH system variable
export PATH=$PATH:/path/to/driver/firefox-driver
Add it to /home//.profile file to make it permanent.
Then you dont need executable_path=''

Can't finalise python set-ups - Subprocesses file causing issues

Firstly, I'd just like to say my level of python programming is absolute beginner so please be patient!
I've installed Python 3.7.4, along with some packages such as numpy, xlwings and (most importantly) selenium.
I've downloaded the this onto my 64-bit windows 10 laptop and followed the advice of the Python forum to address issues particular to Windows but still, when I try to run a slightly modified version of this example code which basically opens a browser (the sample opens firefox, I'm using Chrome - they both have this same issue!), navigates to facebook and logs-in.
My code is:
from selenium import webdriver
import time
username = 'fb_email#email.com'
password = 'fb_password'
url = 'https://www.facebook.com/'
driver = webdriver.Chrome(executable_path=r"C:\\Python37\\Lib\\site-packages\\selenium\\webdriver\\chrome\\webdriver.py")
driver.get(url)
driver.find_element_by_id('email').send_keys(username)
driver.find_element_by_id('pass').send_keys(password)
time.sleep(2)
driver.find_element_by_id('loginbutton').click()
When I run this code I'm getting the following error message:
Traceback (most recent call last):
File
"C:/Python37/Codes/Test.py", line 9, in
driver = webdriver.Chrome(r"C:\Python37\Lib\site-packages\selenium\webdriver\chrome\webdriver.py")

restore_signals, start_new_session) File "C:\Python37\lib\subprocess.py", line 1178, in _execute_child
startupinfo) OSError: [WinError 193] %1 is not a valid Win32 application
You'll notice one other change I've made from the original code is I've include the full file path (explicitly referencing Webdrive.py file) to deal with the "permissions" error.
Basically, I just want to get to the stage I can run this code and I can do I know I can run selenium on python in principal and deal with the nested looping within the python code at a later date so any help/suggestions would be greatly appreciated.

Root Cause:
You are not providing the correct path to the executable_path in line # 9. executable_path should point to the chromedriver.exe path not the p.py path.
How to fix:
Update the line#9 with the correct path to the chromedriver.exe.
# make sure you add `.exe` file name too at the end like `chromedriver.exe`.
driver = webdriver.Chrome(executable_path=r"pathToChromedriver")

Happens this morning and the thing is right after this happens, sometimes when i access website even like google.com, the ERR_ADDRESS_INVALID page shows up often and i need to keep refreshing to get the page back to the regular site.
Is this because that the driver.Chrome() does not include the PATH of Chromedriver location? I used my script for a week before today though and everything worked perfectly.
Please help :(

So if you do not pass a path as a part of the "webdriver.Chrome('path/to/chromedriver')" is will search along the PATH environment variable to find it. So first thing I would do is verify where my chromedriver is. If it is not in $PATH then you can put it in usr/bin and try running again. Or you can pass the path to your chromedriver executable in the .Chrome().
