Edit

It does work when I try this code, but I don't know why it suddenly works Can someone explain this code?

driver=webdriver.Chrome(executable_path="C:/Users\Danny\Downloads\chromedriver_win32\chromedriver.exe")

for i in range(1,10):
driver.get('https://google.com')

The error you are seeing gives us some hint as follows :

WebDriverException                        Traceback (most recent call last)
<ipython-input-36-6bcc3a6d3d05> in <module>()
----> 1 driver.get('https://google.com')

Here are some observations and remedies :

First of all, I would like you to look back at the exact absolute path of the ChromeDriver binary and my guess is instead of :
```
/Users/Users/Downloads/chromedriver_win32/chromedriver
```
It should have been :
```
/Users/Downloads/chromedriver_win32/chromedriver
```
Moreover, a better way to pass the location of the ChromeDriver binary would be to pass the argument executable_path along as well, so the line would be :
```
driver = webdriver.Chrome(executable_path=r'/Users/Users/Downloads/chromedriver_win32/chromedriver')
```
Finally, whenever you invoke get() method to open an URL try to pass the Fully Qualified Domain Name (FQDN) as follows :
```
driver.get('https://www.google.co.in')
```

回答2:

Use this.

from selenium import webdriver
path=r"/Users/Users/Downloads/chromedriver_win32/chromedriver"
driver=webdriver.Chrome(path)
driver.get("https://google.com")

That r in the path stands for "raw" and it might fix your problem.

For what it's worth, I have found that simply restarting my development machine solves this problem for me. It occasionally crops up with no particular explanation, and resolves with a reboot.
