Setup code does not work on Python 3.5.3

Launching up the code and it works beautifully on python 2.7.13 but everything I run on 3.5.3 has the same error message even when I only put in the provided setup code. (Yes my lcd i2c address was 0x27)
I run this code

from RPLCD.i2c import CharLCD
lcd = CharLCD(i2c_expander='PCF8574', address=0x27, port=1,
              cols=20, rows=4, dotsize=8,
              charmap='A02',
              auto_linebreaks=True,
              backlight_enabled=True)

and it always gives the error

Traceback (most recent call last):
  File "/home/pi/Screen.py", line 6, in <module>
    backlight_enabled=True)
  File "/home/pi/.local/lib/python3.5/site-packages/RPLCD/i2c.py", line 164, in __init__
    auto_linebreaks=auto_linebreaks)
  File "/home/pi/.local/lib/python3.5/site-packages/RPLCD/lcd.py", line 99, in __init__
    self.command(0x03)

    self._send_instruction(value)
  File "/home/pi/.local/lib/python3.5/site-packages/RPLCD/i2c.py", line 237, in _send_instruction
    (value & 0xF0)) | self._backlight)
OSError: [Errno 121] Remote I/O error

on python 3.5.3 but it works perfectly fine on python 2.7.13 Not really sure what is going on here. I am running a Pi 3 Model B V1.2 If anything needs clarification drop a comment and if I am posting this in the wrong area tell me where I should be posting it.

After some more debugging I finally narrowed it down to the code giving an error because there was no lcd connected to the i2c port and it appeared a wire had come loose

I Just decided to reinstall the library fro 3.5.3 and it didn’t work I then reinstalled the library on 2.7.13 and rebooted and i works my guess is that the .whl file it installs from using pip was corrupted
