setWeights(weightsArr) {
    weightsArr[0].tensor = unsqueeze(weightsArr[0].tensor).transpose(2, 1, 0, 3)
    this._conv2d.setWeights(weightsArr)
  }
Method for setting layer weights

Override `super` method since weights must be set in `this._conv2d`

@param {Tensor[]} weightsArr - array of weights which are instances of Tensor
