Bug#950463: python3-theano: Installing theano shows SyntaxWarnings (and some questionable code)

[Rogério Brito]

Package: python3-theano
Version: 1.0.4+dfsg-1
Severity: normal


Hi. First of all, thanks for packaging Theano. It is really appreciated.

Now, to the bug report. I was just installing python3-theano now and it
showed some warnings:

,----
| Setting up python3-parameterized (0.7.0-2) ...
| Setting up python3-theano (1.0.4+dfsg-1) ...
| /usr/lib/python3/dist-packages/theano/compile/mode.py:264: SyntaxWarning: "is" with a literal. Did you mean "=="?
|   if optimizer is 'default':
| /usr/lib/python3/dist-packages/theano/gof/op.py:1543: SyntaxWarning: 'str' object is not callable; perhaps you missed a comma?
|   define_macros.append("#define INPUT_%d %s" (i, inp))
| /usr/lib/python3/dist-packages/theano/gof/op.py:1547: SyntaxWarning: 'str' object is not callable; perhaps you missed a comma?
|   define_macros.append("#define OUTPUT_%d %s" (i, inp))
| /usr/lib/python3/dist-packages/theano/gof/opt.py:1287: SyntaxWarning: "is" with a literal. Did you mean "=="?
|   if len(tracks) is 0:
| /usr/lib/python3/dist-packages/theano/gof/tests/test_link.py:116: SyntaxWarning: "is" with a literal. Did you mean "=="?
|   assert 1.0 is fn(1.0)
| /usr/lib/python3/dist-packages/theano/tensor/nnet/bn.py:645: SyntaxWarning: "is" with a literal. Did you mean "=="?
|   return [theano.gradient.DisconnectedType()() if r is 0 else r
| /usr/lib/python3/dist-packages/theano/tensor/nnet/tests/test_conv.py:98: SyntaxWarning: "is not" with a literal. Did you mean "!="?
|   if border_mode is not 'full':
| /usr/lib/python3/dist-packages/theano/tests/test_determinism.py:60: SyntaxWarning: "is not" with a literal. Did you mean "!="?
|   if var.name is not None and var.name is not 'b':
`----

All of these warnings are easy to solve and show some questionable code, like:

,----
|   define_macros.append("#define OUTPUT_%d %s" (i, inp))
`----

It would be great if we could have a new upload with these bugs fixed.


Thanks,

Rogério Brito.
