chrome is not able to run in Selenium Webdriver . i am using selenium 3.0.1 chrome v-54.0
It looks like you are running on a Linux machine, so "chromedriver" (without .exe) should be fine. Just make sure you have the latest chrome and latest chrome driver versions, and also you have the correct "chromedriver" file (the one on 64 bits).
Please check path is correct for chrome driver version https://chromedriver.chromium.org. you need use chrome driver according to which chrome browser version are using
If you are running on windows you need to specify .exe at the end too(Unless you are running on Linux)On a side note try this https://github.com/bonigarcia/webdrivermanager. It will automatically download the driver for you based on your browser and OS. Managing the driver manually is just a waste of time in my opinion.
