AttributeError: module object has nop attribute "OP_NO_TLSv1_1"

dear all,

I have a raspberryPi configured and i follow the guide to download and install the git and other python commands like

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install python-dev
sudo apt-get install python-pip

sudo pip install pymodbus
sudo pip install pycrypto
sudo apt-get install libffi-dev
sudo apt-get install libssl-dev
sudo pip install cryptography

sudo apt-get install sense-hat
sudo reboot

 

afterwards i download the files and run

sudo python SigmaTile_SenseHat_V5.py

 

but i got the below error, any suggestions?

 

pi@raspberrypi:/home/mfg-tile $ sudo python SigmaTile_SenseHat_V5.py
