Installation manual fix

[sapzxc]

Hi!

For centos you need add this to manual: For problems with grpcio and opencv_python: pip3 install --upgrade pip python3 -m pip install --upgrade setuptools

to resolve torchvision install problem: yum install zlib-devel yum install libjpeg-turbo-devel pip3 install "torchvision>=0.9"

pip3 install scikit-build pip3 install -r requirements.txt

my mashine is: Linux server 3.10.0-957.1.3.el7.x86_64

Thanks for the instruction, I will test it soon and add it to the README.md

One more thing, I have tested example code and got error:

# python3.6 test.py

The fix examples here:

textDetector = eu() # brackets here
textDetector.load("latest")

@sapzxc Yes, that's right, you can also apply another design

from NomeroffNet import TextDetector
#...
textDetector = TextDetector.get_static_module("eu")
textDetector.load("latest")
