gradient() throws `ERROR: DimensionMismatch("cannot broadcast array to have fewer dimensions")`

When executing example from README, gs = gradient(x -> sum(tresnet(x)), tip); throws ERROR: DimensionMismatch("cannot broadcast array to have fewer dimensions")

minimal working example (simple Chain substituted for ResNet from README):

using Flux
using Torch
using Torch: torch

net = Chain(
    Dense(10, 5, σ),
    Dense(5, 2),
    softmax)

tnet = net |> torch

ip = rand(Float32, 10, 1)
tip = tensor(ip, dev = 0)

gs = gradient(x -> sum(tnet(x)), tip)

Result:

ERROR: DimensionMismatch("cannot broadcast array to have fewer dimensions")
