[rodluger]

Which version of theano are you running? Can you do

import theano
print(theano.__version__)
print(theano.config)

and let me know what output you get?

[rodluger]

@mikelty Any updates on this?

[mikelty]

here's the output, import gives nothing

>>> print(theano.__version__)
1.1.2
>>> print(theano.config)
floatX ({'float64', 'float16', 'float32'})
    Doc:  Default floating-point precision for python casts.

Note: float16 support is experimental, use at your own risk.
    Value:  float64

warn_float64 ({'ignore', 'warn', 'pdb', 'raise'})
    Doc:  Do an action when a tensor variable with float64 dtype is created. They can't be run on the GPU with the current(old) gpu back-end and are slow with gamer GPUs.
    Value:  ignore

pickle_test_value (<bound method BoolParam._apply of <theano.configparser.BoolParam object at 0x000001CA344AD808>>)
    Doc:  Dump test values while pickling model. If True, test values will be dumped with model.
    Value:  True

cast_policy ({'custom', 'numpy+floatX'})
    Doc:  Rules for implicit type casting
    Value:  custom

deterministic ({'more', 'default'})
    Doc:  If `more`, sometimes we will select some implementation that are more deterministic, but slower. In particular, on the GPU, we will avoid using AtomicAdd. Sometimes we will still use non-deterministic implementaion, e.g. when we do not have a GPU implementation that is deterministic. Also see the dnn.conv.algo* flags to cover more cases.
    Value:  default

device (cpu, opencl*, cuda*)
    Doc:  Default device for computations. If cuda* or opencl*, change thedefault to try to move computation to the GPU. Do not use upper caseletters, only lower case even if NVIDIA uses capital letters. 'gpu' means let the driver select the gpu (needed for gpu in exclusive mode). 'gpuX' mean use the gpu number X.
    Value:  cpu

init_gpu_device (, opencl*, cuda*)
    Doc:  Initialize the gpu device to use, works only if device=cpu. Unlike 'device', setting this option will NOT move computations, nor shared variables, to the specified GPU. It can be used to run GPU-specific tests on a particular GPU.
    Value:

force_device (<bound method BoolParam._apply of <theano.configparser.BoolParam object at 0x000001CA34519788>>)
    Doc:  Raise an error if we can't use the specified device
    Value:  False

conv__assert_shape (<bound method BoolParam._apply of <theano.configparser.BoolParam object at 0x000001CA34519808>>)
    Doc:  If True, AbstractConv* ops will verify that user-provided shapes match the runtime shapes (debugging option, may slow down compilation)
    Value:  False

print_global_stats (<bound method BoolParam._apply of <theano.configparser.BoolParam object at 0x000001CA345198C8>>)
    Doc:  Print some global statistics (time spent) at the end
    Value:  False

<theano.configparser.ContextsParam object at 0x000001CA34519988>
    Doc:
        Context map for multi-gpu operation. Format is a
        semicolon-separated list of names and device names in the
        'name->dev_name' format. An example that would map name 'test' to
        device 'cuda0' and name 'test2' to device 'opencl0:0' follows:
        "test->cuda0;test2->opencl0:0".

        Invalid context names are 'cpu', 'cuda*' and 'opencl*'

    Value:

print_active_device (<bound method BoolParam._apply of <theano.configparser.BoolParam object at 0x000001CA34519A08>>)
    Doc:  Print active device at when the GPU device is initialized.
    Value:  True

gpuarray__preallocate (<class 'float'>)
    Doc:  If negative it disables the allocation cache. If
                 between 0 and 1 it enables the allocation cache and
                 preallocates that fraction of the total GPU memory.  If 1
                 or greater it will preallocate that amount of memory (in
                 megabytes).
    Value:  0.0

gpuarray__sched ({'single', 'default', 'multi'})
    Doc:  The sched parameter passed for context creation to pygpu.
                    With CUDA, using "multi" is equivalent to using the parameter
                    cudaDeviceScheduleBlockingSync. This is useful to lower the
                    CPU overhead when waiting for GPU. One user found that it
                    speeds up his other processes that was doing data augmentation.

    Value:  default

gpuarray__single_stream (<bound method BoolParam._apply of <theano.configparser.BoolParam object at 0x000001CA34519BC8>>)
    Doc:
                 If your computations are mostly lots of small elements,
                 using single-stream will avoid the synchronization
                 overhead and usually be faster.  For larger elements it
                 does not make a difference yet.  In the future when true
                 multi-stream is enabled in libgpuarray, this may change.
                 If you want to make sure to have optimal performance,
                 check both options.

    Value:  True

    Doc:  Do we default to delete intermediate results during Theano function calls? Doing so lowers the memory requirement, but asks that we reallocate memory at the next function call. This is implemented for the default linker, but may not work for all linkers.

    Doc:  Allow unpickling of pickled GpuArrays as numpy.ndarrays.This is useful, if you want to open a GpuArray without having cuda installed.If you have cuda installed, this will force unpickling tobe done on the cpu to numpy.ndarray.Please be aware that this may get you access to the data,however, trying to unpicke gpu functions will not succeed.This flag is experimental and may be removed any time, whengpu<>cpu transparency is solved.

check_input (<bound method BoolParam._apply of <theano.configparser.BoolParam object at 0x000001CA34528F08>>)
    Doc:  Specify if types should check their input in their C code. It can be used to speed up compilation, reduce overhead (particularly for scalars) and reduce the number of generated C files.

Hey @mikelty the issue seems to be that there isn't a C++ compiler available to theano (see the cxx property). You probably get a warning saying that C++ ops are disabled when you import theano, and that it will fallback to Python ops (right?). The starry ops require C++, so you'll need to make one available to theano in order to get it to work.

I've usually seen this issue on Windows when using the built-in Python installation. I'd recommend using the Anaconda distribution (https://www.anaconda.com/products/individual), which ships with the g++ compiler and should fix the issues you're having. Alternatively, you can look at what people posted here for other ideas -- this seems to be a common issue.
