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.
