Returns whether TensorFlow can access a GPU. (deprecated)
tf.test.is_gpu_available( cuda_only=False, min_cuda_compute_capability=None )
Used in the tutorials:
cuda_only: limit the search to CUDA GPUs.
min_cuda_compute_capability: a (major,minor) pair that indicates the minimum CUDA compute capability required, or None if no requirement.
Note that the keyword arg name "cuda_only" is misleading (since routine will return true when a GPU device is available irrespective of whether TF was built with CUDA support or ROCm support. However no changes here because
++ Changing the name "cuda_only" to something more generic would break backward compatibility
++ Adding an equivalent "rocm_only" would require the implementation check the build type. This in turn would require doing the same for CUDA and thus potentially break backward compatibility
++ Adding a new "cuda_or_rocm_only" would not break backward compatibility, but would require most (if not all) callers to update the call to use "cuda_or_rocm_only" instead of "cuda_only"
True if a GPU device of the requested kind is available.
