Confirmed that this issue also happens in numpy branch. Since instance norm was using a legacy operator interface, I will refactor it to use the new operator interface and register an npx namespace alias. ``` from mxnet import np, npx npx.set_np() input = np.random.rand(0,1,1) # batch = 0 gamma = np.random.rand(1) beta = np.random.rand(1) npx.instance_norm(input, gamma, beta) ``` ``` from mxnet import np, npx npx.set_np() input = mxnet.nd.array(np.random.rand(1,0,1)) # channel = 0 gamma = np.random.rand(1) beta = np.random.rand(1) npx.instance_norm(input, gamma, beta) ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
