XInitialize opened a new issue #20344: URL: https://github.com/apache/incubator-mxnet/issues/20344
## Description I used [cross-compilation](https://mxnet.apache.org/get_started/jetson_setup) to compile the Jetson version of MXNet (v1.8.0). When I executed the script to test mxnet installation, I found an error in ‘import mxnet as mx’ ### Error Message > Traceback (most recent call last): > File "test_mxnet.py", line 2, in <module> > import mxnet as mx > File "/home/xzw/mxnet/python/mxnet/__init__.py", line 83, in <module> > from . import gluon > File "/home/xzw/mxnet/python/mxnet/gluon/__init__.py", line 38, in <module> > from . import data > File "/home/xzw/mxnet/python/mxnet/gluon/data/__init__.py", line 30, in <module> > from . import _internal > File "/home/xzw/mxnet/python/mxnet/gluon/data/_internal.py", line 265, in <module> > _init_internal_dataset_module() > File "/home/xzw/mxnet/python/mxnet/gluon/data/_internal.py", line 258, in _init_internal_dataset_module > check_call(_LIB.MXListDatasets(ctypes.byref(size), ctypes.byref(plist))) > File "/usr/lib/python3.6/ctypes/__init__.py", line 361, in __getattr__ > func = self.__getitem__(name) > File "/usr/lib/python3.6/ctypes/__init__.py", line 366, in __getitem__ > func = self._FuncPtr((name_or_ordinal, self)) > AttributeError: libmxnet.so: undefined symbol: MXListDatasets ## To Reproduce - cross-compilation (change some files for bad network connection) File: ci/docker/Dockerfile.build.jetson line49 add(already clone ccache): `COPY ccache /work/deps/ccache` line54,55 (already clone OpenBLAS): ``` COPY OpenBLAS /usr/local/OpenBLAS # RUN git clone --recursive -b v0.3.9 https://github.com/xianyi/OpenBLAS.git && \ ``` File: ci/build.py line73-81: ``` try: with open(filename,"rb") as f: while True: d = f.read(bufsiz) if not d: break ctx.update(d) except IsADirectoryError: pass ``` then follow the official guide ### Steps to reproduce (Paste the commands you ran that produced the error.) on server ``` scp build/mxnet-1.8.0-py3-none-any.whl xxxxx:~/mxnet-1.8.0-py3-none-any.whl scp build/libmxnet.so xxxxx:~/libmxnet.so ``` on Jetson Nano(2GB) ``` pip3 install mxnet-1.8.0-py3-none-any.whl echo "import mxnet as mx">test_mxnet.py python3 test_mxnet.py ``` ## What have you tried to solve it?
