want to update this case and share some my experiences with the community...
I have finally successfully cross-complied the mxnet for armv7 (Pi) - the whl
file instructed in the mxnet doc. The way I resolved it is using the latest
1.3.0 source instead of the 1.2.1 that gave me problems. thx the the CI build
from the mxnet team I guess :-)
I am following the next step to install the whl package with pip command under
a virtualenv.
It looks the mxnet package is installed successfully too.
However, when I tried to test by import mxnet as mx under python interpreter, I
got an error indicating:
OSError: /... path to libmxnet.so : cannot open shared object file. No sun file
or directory
To get around this, I add the path to the libmxnet.so using:
>>> import sys
>>> sys.path.append(path to the libmxnet.so)
alternatively, I would need to run the python interpreter in the same directory
of libmxnet.so.
(btw, I saw the sys.path has this path -
'/home/pi/my_mxnet_work/mxnet_py3/lib/python3.4/site-packages, inserted in the
end. I assume that's added by the build script. if so, I am wondering if the
script should add
'/home/pi/my_mxnet_work/mxnet_py3/lib/python3.4/site-packages/mxnet' in the
path as well? )
However, I run into another problem about ImportError - see output below.
I saw quiet few discussions about this error in the past but still not sure how
to resolve it yet.
I will dig out more but just to update this case in case someone has insights
