Descriptions

TensorFlow is an end-to-end open source platform for machine learning. Calling `tf.raw_ops.ImmutableConst`(https://www.tensorflow.org/api_docs/python/tf/raw_ops/ImmutableConst) with a `dtype` of `tf.resource` or `tf.variant` results in a segfault in the implementation as code assumes that the tensor contents are pure scalars. We have patched the issue in 4f663d4b8f0bec1b48da6fa091a7d29609980fa4 and will release TensorFlow 2.5.0 containing the patch. TensorFlow nightly packages after this commit will also have the issue resolved. If using `tf.raw_ops.ImmutableConst` in code, you can prevent the segfault by inserting a filter for the `dtype` argument.

TensorFlow es una plataforma de código abierto de extremo a extremo para el aprendizaje automático. Llamar a "tf.raw_ops.ImmutableConst" (https://www.tensorflow.org/api_docs/python/tf/raw_ops/ImmutableConst) con un" dtype" de "tf.resource" o" tf.variant" resulta en un fallo de segmentación en una implementación como código se asume que los contenidos del tensor son escalares puros. Hemos parcheado el problema en 4f663d4b8f0bec1b48da6fa091a7d29609980fa4 y lanzaremos TensorFlow versión 2.5.0 que contiene el parche. Los paquetes nocturnos de TensorFlow después de este commit también resolverán el problema. Si usa "tf.raw_ops.ImmutableConst" en el código, puede impedir el fallo de segmentación al insertar un filtro para el argumento "dtype"
