/_fastestrplidar.so: wrong ELF class: ELFCLASS64

[Eric-nguyen1402]

After I finished installing the fastestrplidar library when I ran this example :
`
from fastestrplidar import FastestRplidar

if name == 'main':
# Initialize the library and creates and object
lidar = FastestRplidar()

# connects the lidar using the default port (tty/USB0)
lidar.connectlidar()
# Starts the lidar motor
lidar.startmotor()
# fetches the lidar scan data
result = lidar.fetchscandata()
print ("result - ")
print (result)

# done. Stops the motor
lidar.stopmotor()

`
I meet this error: /_fastestrplidar.so: wrong ELF class: ELFCLASS64 and the _fastestrplidar.so file is empty. Has anyone had a solution for this problem?
