run train.py

When I run train.trainer() .here are much mistake.Can you meet this problem?

I face the same issue with u now.would you solve it, please?

In optim.py change gshared to gshared = [theano.shared(p.get_value().astype('float32'), name='%s_grad'%k) for k, p in tparams.items()]

and in the loop that appends values to 'updates' add:
m = theano.shared(p.get_value().astype(numpy.float32))
v = theano.shared(p.get_value().astype(numpy.float32))
