reminisce commented on issue #16098: [Bug] Unrecognize parameter shape after npx.set_up()

   It looks like you saved a net which has not been initialized. It should work like the following. However, recent changes on ndarray indexing has prevented assigning a legacy `NDArray` to `mxnet.numpy.ndarray`. So the `load` function cannot work now. I will submit a PR to fix this.
   ```python
   from mxnet import npx, np
   npx.set_np()
   from mxnet.gluon import nn
   print(nn.Dense(32).collect_params())  # weight shape=(32,-1)
   
   net = nn.Dense(32)
   net.initialize()
   net(np.ones((4, 11)))
   print(net.collect_params())  # weight shape=(32,-1)
   
   net.save_parameters('test.params')
   net.load_parameters('test.params')
   print(net.collect_params())
   ```
