xhpohanka opened a new issue #7508: Importing caffe in python causes mxnet leaky relu to output wrong results
URL: https://github.com/apache/incubator-mxnet/issues/7508
 
 
   I have very strange issue on my workstation
   After importing caffe python module any slope less than `1.0` causes results to be zero. Please check example below.
   I have also another installation of mxnet on another machine (almost same) and there everything works fine.
   
   ```
   import mxnet as mx
   import numpy as np
   d = np.ones((1, 3, 5,5))*-1
   dd = mx.nd.array(d)
   mx.nd.LeakyReLU(data=dd, act_type='leaky', slope=0.2).asnumpy()
   array([[[[-0.2, -0.2, -0.2, -0.2, -0.2],
            [-0.2, -0.2, -0.2, -0.2, -0.2],
            [-0.2, -0.2, -0.2, -0.2, -0.2],
            [-0.2, -0.2, -0.2, -0.2, -0.2],
            [-0.2, -0.2, -0.2, -0.2, -0.2]],
   
           [[-0.2, -0.2, -0.2, -0.2, -0.2],
            [-0.2, -0.2, -0.2, -0.2, -0.2],
            [-0.2, -0.2, -0.2, -0.2, -0.2],
            [-0.2, -0.2, -0.2, -0.2, -0.2],
            [-0.2, -0.2, -0.2, -0.2, -0.2]],
   
           [[-0.2, -0.2, -0.2, -0.2, -0.2],
            [-0.2, -0.2, -0.2, -0.2, -0.2],
            [-0.2, -0.2, -0.2, -0.2, -0.2],
            [-0.2, -0.2, -0.2, -0.2, -0.2],
            [-0.2, -0.2, -0.2, -0.2, -0.2]]]], dtype=float32)
   
   import caffe
   mx.nd.LeakyReLU(data=dd, act_type='leaky', slope=0.2).asnumpy()
   array([[[[-0., -0., -0., -0., -0.],
            [-0., -0., -0., -0., -0.],
            [-0., -0., -0., -0., -0.],
            [-0., -0., -0., -0., -0.],
            [-0., -0., -0., -0., -0.]],
   
           [[-0., -0., -0., -0., -0.],
            [-0., -0., -0., -0., -0.],
            [-0., -0., -0., -0., -0.],
            [-0., -0., -0., -0., -0.],
            [-0., -0., -0., -0., -0.]],
   
           [[-0., -0., -0., -0., -0.],
            [-0., -0., -0., -0., -0.],
            [-0., -0., -0., -0., -0.],
            [-0., -0., -0., -0., -0.],
            [-0., -0., -0., -0., -0.]]]], dtype=float32)
   ```
