TypeError: 'NotImplementedType' object is not callable, in codegen("C")

[alexvoronov]

Hi,

I get the following error when running codegen for C:

Traceback (most recent call last):
  File "bug_report.py", line 13, in <module>
    p.codegen("C")
  File "/usr/local/lib/python2.7/site-packages/qcml/helpers.py", line 29, in wrap
    result = func(*args, **kwargs)
  File "/usr/local/lib/python2.7/site-packages/qcml/qc_lang.py", line 103, in codegen
    self.__codegen.codegen()
  File "/usr/local/lib/python2.7/site-packages/qcml/codegens/base_codegen.py", line 132, in codegen
    self.prob2socp.create()
  File "/usr/local/lib/python2.7/site-packages/qcml/codes/function.py", line 86, in create
    self.__source = self._generate_source(self.code)
  File "/usr/local/lib/python2.7/site-packages/qcml/codes/function.py", line 92, in code

    self.__body.append("{:}{:}".format(self.indent, line).rstrip() for line in iterable_line(lines))
  File "/usr/local/lib/python2.7/site-packages/qcml/codegens/C/codegen.py", line 315, in stuff_c
    yield "for(i = 0; i < %s; ++i) data->c[i + %s] = %s%s" % (end-start, start, toC(expr), tag)
  File "/usr/local/lib/python2.7/site-packages/qcml/codes/encoders/encoder.py", line 6, in encode
    return lookup[x.__class__](x)
TypeError: 'NotImplementedType' object is not callable

It might be related to #41, since minimal example where I get it is the same:

#!/usr/bin/env python
from qcml import QCML

if __name__ == '__main__':

    s = ("""variables x(2)
    minimize sum(3*x)""")

    p = QCML()
    p.parse(s)

    p.canonicalize()
    p.codegen("C")

Thanks! I'll take a look at this,

Okay, give it a shot now; I should have fixed it.

Thanks Eric, now it works with a vector. It does not work with a matrix though:

#!/usr/bin/env python
from qcml import QCML

if __name__ == '__main__':

    s = ("""variable x(2)
        parameter D(2,2)
        minimize sum(D*x)""")

    p = QCML(debug=False)
    p.parse(s)

    p.canonicalize()
    p.codegen("C")

results in

...
  File "/usr/local/lib/python2.7/site-packages/qcml/codegens/C/codegen.py", line 315, in stuff_c
    yield "for(i = 0; i < %s; ++i) data->c[i + %s] = %s%s" % (end-start, start, toC(expr), tag)
  File "/usr/local/lib/python2.7/site-packages/qcml/codes/encoders/encoder.py", line 7, in encode
    return lookup[x.__class__](x)
TypeError: 'NotImplementedType' object is not callable

okay. i pushed something; give it a shot and let me know if it works.

Thanks a lot, now codegen produces the output! But it seems like the output of the codegen is not entirely perfect. For the example above, it uses undeclared variable result, here is a snippet:

    /* allocate A matrix */
    nnzA = 1*result->nnz + 2;

So when I try to compile it, I get a compilation error:

error: use of undeclared identifier 'result'

Am I missing some include that has this result declared somewhere globally, or is it just the declaration of a qc_matrix result = ... missing in the beginning of the function? I looked through generated code for python to get inspiration how such matrix can look like, but there is no result variable in Python...

sorry for the slow response, i've been traveling.

so, what's your problem spec? on that same line, i have

1*params->D->nnz + 2;

Very strange... I will open a new issue and post my source and generated code there
