1. run in PC
In aitf framework run below command:
python3 -m pytest -k "LBSP-AI-ZY-BuildSIM-ESRGAN"
This command will compiler the esrgan model, prepare the test data
and do inference in PC and FWD mode.
The compiled model, quantized input and pc, fwd reference output 
are stored in output folder of aitf named with case names

2. check result of PC
Go to the case folder like: LBSP-AI-ZY-BuildSIM-ESRGAN-SM-0102/opath
There are pictures to store the orginal pic, resize pic, sr pic by pc infer,
sr pic for fwd mode.
The picture named like: fwd_pic9.png

3. run in board
Use the c++ or python inference tool to run thie built aipu.bin and feed
the quantized input to get the inference output result.

4. check the result of board
In board or in PC cp the sr_compare.py to opath folder, then run:
python3 sr_compare.py srgan or python3 sr_compare.py esrgan. 
It will generate the comparing picture of sr images from fwd and board running.
These pictures are named like: gan_cmp_pic{idx}.png
