The size of tensor a (100) must match the size of tensor b (64) at non-singleton dimension 2"

I am trying to implement a simple linear network.

The input tensor size is (B,3,64,64)

My network is defined like this.

    tensorSize = x.size()
    input = tensorSize[0] * tensorSize[1] * tensorSize[2]
    self.linear_one = torch.nn.Linear(64, input)
    self.linear_two = torch.nn.Linear(input, 32)
    self.linear_output = torch.nn.Linear(32, 6)
    self.layer_in = self.linear_one(x)
    self.layer_in_two = self.linear_two(self.layer_in)
    self.layer_out = self.linear_output(self.layer_in_two)

My output is size (B,3,64,6) but it needs to be (B,6)

Why is my network not outputting the correct results?

Prop `className` did not match in next js app

I have written a sample code ( Github Link here ). this is a simple next js app, but giving me error when I refresh the page. This seems to be the common problem and I tried the fix provided in the internet but does not seem to fix my issue. The error is Warning: Prop className did not match. Server: "MuiBox-root MuiBox-root-1" Client: "MuiBox-root MuiBox-root-2". Did changes for _document.js, modified _app.js as mentioned in official website and solutions in stackoverflow. but nothing seems to work. Could someone take a look and help me whats wrong with the code? Via Active questions tagged javascript - Stack Overflow https://ift.tt/2FdjaAW
