Geckodriver not working on Raspberry Pi

I am trying to install InstaPy on the Raspberry Pi (raspbian).

I'm not sure whether instapy is calling the correct gckodriver from usr/local/bin. How can I ensure this? Path is:
```pi@raspberrypi:~ $ echo $PATH
/home/pi/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games
```

But I'm getting following error.
```

Even starting geckodriver directly is not working.
