a550461053 opened a new issue #17577: build mxnet from source and get ImportError: cannot import name 'NDArrayHandle' URL: https://github.com/apache/incubator-mxnet/issues/17577 - I build mxnet from source, here's the steps: ``` git clone --recursive https://github.com/apache/incubator-mxnet cd incubator-mxnet cp make/config.mk ./ # change config.mk to set: USE_OPENCV=1 USE_BLAS=openblas USE_CUDA=1 USE_CUDA_PATH=/usr/local/cuda USE_CUDNN=1 USE_DIST_KVSTORE=1 USE_NCCL=0 make -j $(nproc) cd python/ && pip install --user -e . ``` - I got `ImportError: cannot import name 'NDArrayHandle` when I test mxnet in python. `from mxnet.kvstore import NDArrayHandle` - Then I list the kvstore class: 1. In release mxnet-cu100: ``` >>> import mxnet.kvstore as kv >>> dir(kv) ['KVStore', 'KVStoreHandle', 'NDArray', 'NDArrayHandle', '_LIB', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '_ctype_dict', '_ctype_key_value', '_get_kvstore_server_command_type', '_ndarray_cls', '_updater_wrapper', 'absolute_import', 'array', 'c_array', 'c_array_buf', 'c_handle_array', 'c_str', 'c_str_array', 'check_call', 'create', 'ctypes', 'mx_uint', 'opt', 'pickle', 'py_str', 'set_kvstore_handle', 'string_types'] ``` 2. In my build mxnet: ``` >>> dir(kv) │· ['KVStore', 'KVStoreBase', 'KVStoreServer', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__pa│· ckage__', '__path__', '__spec__', 'base', 'create', 'kvstore', 'kvstore_server'] ``` I want to know why it happen and what's the default `config.mk` of the released mxnet wheel.
