tf.fft2d(input, name=None) Compute the 2-dimensional discrete Fourier Transform over the inner-most 2 dimensions of input. Args: input: A Tensor of type complex64. A complex64 tensor. name: A name for the operation (optional). Returns: A Tensor of type complex64. A complex64 tensor of the same shape as input. The inner-most 2 dimensions of input are replaced with their 2D Fourier Transform.

tf.fft(input, name=None) Compute the 1-dimensional discrete Fourier Transform over the inner-most dimension of input. Args: input: A Tensor of type complex64. A complex64 tensor. name: A name for the operation (optional). Returns: A Tensor of type complex64. A complex64 tensor of the same shape as input. The inner-most dimension of input is replaced with its 1D Fourier Transform.

tf.exp(x, name=None) Computes exponential of x element-wise. \(y = e^x\). Args: x: A Tensor. Must be one of the following types: half, float32, float64, complex64, complex128. name: A name for the operation (optional). Returns: A Tensor. Has the same type as x.

tf.errors.UnknownError.__init__(node_def, op, message, error_code=2) Creates an UnknownError.

class tf.errors.UnknownError Unknown error. An example of where this error may be returned is if a Status value received from another address space belongs to an error-space that is not known to this address space. Also errors raised by APIs that do not return enough error information may be converted to this error.

tf.errors.UnimplementedError.__init__(node_def, op, message) Creates an UnimplementedError.

class tf.errors.UnimplementedError Raised when an operation has not been implemented. Some operations may raise this error when passed otherwise-valid arguments that it does not currently support. For example, running the tf.nn.max_pool() operation would raise this error if pooling was requested on the batch dimension, because this is not yet supported.

tf.errors.UnavailableError.__init__(node_def, op, message) Creates an UnavailableError.

class tf.errors.UnavailableError Raised when the runtime is currently unavailable. This exception is not currently used.

tf.errors.UnauthenticatedError.__init__(node_def, op, message) Creates an UnauthenticatedError.
