sudo apt-get install libupm-dev is not working i tried to import upm not it says module not found
but import mraa is working fine
libXXX-dev is usually for C development but you said you tried import upm which suggests you are using python rather then C. For python packages would usually look like python-XXX (e.g. python-upm).
yes, i tried but result is same 
Sorry, just remembered there are some known probems with this package. See:
https://bugs.96boards.org/show_bug.cgi?id=457
In short the workaround you need are:
- Run
export PYTHONPATH=/usr/lib/aarch64-linux-gnu/python2.7/site-packages/(this is a bit of a pain because it stops sudo working correctly. - Apply additional special changes if you want pyupm_i2clcd to work correctly (remove the non-ASCII characters from the comments)
- You can’t import upm directly (I think because the package is too old). Try to import the modules directly:
import pyupm_a110xor alternatively if you are working with examples that use the following idiomfrom upm import pyupm_a110x as upmA110xthen change them toimport pyupm_a110x as upmA110xinstead.
ok let suppose i don’t have upm now tell me what is the first step
is there any tutorial video on that how to use upm libraries
You need to build and install libupm from source as mentioned here.
PS: I assume that you have installed MRAA
Debian UPM package has been updated to latest version 1.6.0. So try to upgrade “python-upm” package using following cmd:
sudo apt upgrade python-upm
With upgrade successful, imports should work fine as follows:
>>> import upm
>>> from upm import pyupm_lcd
