viper7882 commented on issue #13040: Import and GPU init extremely slow on Windows URL: https://github.com/apache/incubator-mxnet/issues/13040#issuecomment-438239629 A simple program and memory profiling explains the reason of slowness. `import mxnet as mx if __name__ == '__main__': a = mx.nd.ones((2, 3), mx.gpu()) b = a * 2 + 1 print (b.asnumpy())`  The peak memory usage has exceeded 2GB using this simple program. Likely someone has loaded huge amount of library contents into the RAM. My best guess would be cu92mkl as stated in [installation guide here](https://mxnet.incubator.apache.org/install/index.html?platform=Windows&language=Python&processor=GPU). Unless you always have vacant 2-4GB of RAM, else loading mxnet 1.3.0 will be slow due to Windows have to spend time to load from disk to RAM. Btw, I'm using SSD and still experience slowness.
