ArmageddonKnight opened a new issue #10356: MXNet from Source is slower than Pip Package
URL: https://github.com/apache/incubator-mxnet/issues/10356
 
 
   Hi there,
   
   I have two copies of `MXNet` - one local copy that I kept for revision and another global copy which has been installed using `sudo -H pip3 install mxnet-cu80==0.12.1`. I built my local copy using the following command:
   
   ```
   make -j $(nproc) \
   	USE_OPENCV=1 USE_BLAS=openblas USE_CUDA=1 \
   	USE_CUDA_PATH=/usr/local/cuda USE_CUDNN=1 USE_CPP_PACKAGE=1
   ```
   
   and created a virtual environment for the python binding. The problem is that - when I run the `cudnn_lstm_bucketing.py` example, what I noticed is that the local copy (throughput is around `3600 samples/sec`) is around `1000 samples/sec` slower than the global copy (throughput is around `4600 samples/sec`).
   
   Could someone please tell me whether I am missing some build options in my `make` command? Thank you.
