MethodError: no method matching maxpool(::Array{Float32,4}, ::Tuple{Int64,Int64})

When running the test, GoogleNet() model, all get this error.

Here is the runtest result:

[avik-pal]

Is this the master branch? (If not install the master and run the tests)

[barcoyou]

yes, I just clone it from the master branch

[barcoyou]

solved!
the maxpool interface is deprecated.
Should use MaxPool
