Unable to run sorry. could you release the steps from initial environment to running the code?

[dongdyang]

My environment is set to the same as the author.

However, I still met this problem. Unable to fix it.
Could you release the steps from initial environment to running the code?
Thanks!

m_cost, _ = theano.scan(fn=merge_cost,
                     sequences=[network_output_softmax, target_values.T, l_mask.input_var.T],
                     outputs_info=T.constant(0))

When I run the code, the error information is as followings:
Learnableness: [True, True, False]
Using 0.001 for off_slope.

ValueError: When compiling the inner function of scan the following error has been encountered: The initial state (outputs_info in scan nomenclature) of variable IncSubtensor{Set;:int64:}.0 (argument number 3) has dtype int8, while the result of the inner function (fn) has dtype float64. This can happen if the inner function of scan results in an upcast or downcast.

@tonnkie

It seems that you are using python3.6. And the error seems about the upcast or downcast of different dtypes (int8 and float64).
Can you try python2.7 please? Since we tested our code with python2.7.

If some environments are missing, you can tell me. And I will show more initial environments.
