i am trying to run this program https://github.com/npow/ubottu for making a model for Ubuntu Dialog Corpus
It uses Theano and Lasagne as dependencies. when i install Theano and Lasagne from pip, and do a simple import lasagne i get the error from theano.tensor.signal import downsampleImportError: cannot import name 'downsample' then found a workaround here, https://stackoverflow.com/questions/42998355/lasagne-vs-theano-possible-version-mismatch-windows suggestion was to install Theano and Lasagne from their github master branches respectively pip install --upgrade https://github.com/Theano/Theano/archive/master.zip pip install --upgrade https://github.com/Lasagne/Lasagne/archive/master.zip This removed the above erorr, but i am getting the following error. TypeError: ('An update must have the same type as the original shared variable (shared_var=hid_init, shared_var.type=TensorType(float64, row), update_val=Elemwise{sub,no_inplace}.0, update_val.type=TensorType(float64, matrix)).', 'If the difference is related to the broadcast pattern, you can call the tensor.unbroadcast(var, axis_to_unbroadcast[, ...]) function to remove broadcastable dimensions.') it seems that there is a type mismatch somewhere. a variable of row type is updated with a value of matrix type.
