I've followed the docker installation guide and choose the "privileged mode" install.
Starting with the basic install:
git clone -b ncsdk2 http://github.com/Movidius/ncsdk && cd ncsdk
After installing the sdk, compiling graphs worked ok.
Later on I cloned the example apps with:
git clone -b ncsdk2 https://github.com/movidius/ncappzoo.git
Then I tried making the hello_ncs_py and this failed with the following error:
root@# python3 hello_ncs_api2.py W: [ 0] ncDeviceOpen:528 ncDeviceOpen() XLinkBootRemote returned error 3 Error - Could not open NCS device. root@# python3 hello_ncs.py Error - Could not open NCS device.
Finally, I went back and tried to compile the same exact graph that was working previously and it didn't work.
