theano.gpu.config

floatX (('float64', 'float32', 'float16')) 
    Doc:  Default floating-point precision for python casts.

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

warn_float64 (('ignore', 'warn', 'raise', 'pdb')) 
    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.

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

int_division (('int', 'raise', 'floatX')) 
    Doc:  What to do when one computes x / y, where both x and y are of integer types
    Value:  int

device (cpu, gpu*, 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.
    Value:  cuda0

init_gpu_device (, gpu*, 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 (<function BoolParam.<locals>.booltype at 0x7f2214c72268>) 
    Doc:  Raise an error if we can't use the specified device

conv.assert_shape (<function BoolParam.<locals>.booltype at 0x7f2214c72400>) 
    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 (<function BoolParam.<locals>.booltype at 0x7f2214c72598>) 
    Doc:  Print some global statistics (time spent) at the end
    Value:  False

<theano.configdefaults.ContextsParam object at 0x7f2215325898>
    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 (<function BoolParam.<locals>.booltype at 0x7f2214c72840>)

cuda.root (<class 'str'>) 
    Doc:  directory with bin/, lib/, include/ for cuda utilities.
       This directory is included via -L and -rpath when linking
       dynamically compiled modules.  If AUTO and nvcc is in the
       path, it will use one of nvcc parent directory.  Otherwise
       /usr/local/cuda will be used.  Leave empty to prevent extra
       linker directives.  Default: environment variable "CUDA_ROOT"
       or else "AUTO".
       
    Value:  /usr/local/cuda

cuda.enabled (<function BoolParam.<locals>.booltype at 0x7f2214c72c80>)

    Doc:  
    Value:  True

nvcc.cudafe (('always', 'heuristic')) 
    Doc:  If 'always' (the default), cudafe will be called for every GPU Op compilation. If 'heuristic', it will only be called if the source code appears to contain CUDA code. This can speed up compilation and importing theano, but might fail to compile some custom GPU Ops.
    Value:  always

gpuarray.sync (<function BoolParam.<locals>.booltype at 0x7f2214c741e0>) 
    Doc:  If True, every op will make sure its work is done before
                returning.  Setting this to True will slow down execution,
                but give much more accurate results in profiling.
    Value:  False

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 (('default', 'multi', 'single')) 
    Doc:  The sched parameter passed for context creation to pygpu.
                With CUDA, using "multi" is equivalent to using the parameter
                cudaDeviceScheduleYield. 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 (<function BoolParam.<locals>.booltype at 0x7f2214c74488>) 
    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

    Value:  cvm

allow_gc (<function BoolParam.<locals>.booltype at 0x7f2214c7f8c8>) 
    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:  If 'None', we warn about all Theano bugs found by default. If 'all', we don't warn about Theano bugs found by default. If a version, we print only the warnings relative to Theano bugs found after that version. Warning for specific bugs can be configured with specific [warn] flags.

    Doc:  Your current code is fine, but Theano versions prior to 0.7 (or this development version) might have given an incorrect result. To disable this warning, set the Theano flag warn.reduce_join to False. The problem was an optimization, that modified the pattern "Reduce{scalar.op}(Join(axis=0, a, b), axis=0)", did not check the reduction axis. So if the reduction axis was not 0, you got a wrong answer.

print_test_value (<function BoolParam.<locals>.booltype at 0x7f2214c87158>) 
    Doc:  If 'True', the __eval__ of a Theano variable will return its test_value when this is available. This has the practical conseguence that, e.g., in debugging `my_var` will print the same as `my_var.tag.test_value` when a test value is defined.

It is preferable to define it via the Theano configuration file ~/.theanorc or with the environment variable THEANO_FLAGS. Parallelization is only done for some operations that implement it, and even for operations that implement parallelism, each operation is free to respect this flag or not. You can control the number of threads used with the environment variable OMP_NUM_THREADS. If it is set to 1, we disable openmp in Theano by default.
