That's the C++ core library not the python binding

Please see the above link for doc. Generally speaking, you need to install Python MNN package. command line like pip install -U MNN

@stanleywang8888 I know. I'm working on raspberrypi so I can not install It from pip. Do you have any suggestion ?

stanleywang8888 commented 5 years ago

Sorry, Python package depends on pip, either you can try to solve the pip issue, or you can try the c++ interface.

Hi @buiduchanh , We are using nvidia jetson nano, We are able to build for c++ but unable get the python bindings. We have given the pip3 command and got the error as below

nvdia@nvdia-desktop:~$ sudo pip3 install -U MNN ERROR: Could not find a version that satisfies the requirement MNN (from versions: none) ERROR: No matching distribution found for MNN

Can you please share the steps you followed for raspberry pi so that we can try on our board. Any help is much appreciated. Thanks and regards
