Descriptions

TensorFlow is an open source platform for machine learning. `tf.keras.losses.poisson` receives a `y_pred` and `y_true` that are passed through `functor::mul` in `BinaryOp`. If the resulting dimensions overflow an `int32`, TensorFlow will crash due to a size mismatch during broadcast assignment. We have patched the issue in GitHub commit c5b30379ba87cbe774b08ac50c1f6d36df4ebb7c. The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1 and 2.9.3, as these are also affected and still in supported range. However, we will not cherrypick this commit into TensorFlow 2.8.x, as it depends on Eigen behavior that changed between 2.8 and 2.9.

TensorFlow es una plataforma de código abierto para aprendizaje automático. `tf.keras.losses.poisson` recibe `y_pred` y `y_true` que se pasan a través de `functor::mul` en `BinaryOp`. Si las dimensiones resultantes desbordan un `int32`, TensorFlow fallará debido a una discrepancia de tamaño durante la asignación de transmisión. Hemos solucionado el problema en el commit de GitHub c5b30379ba87cbe774b08ac50c1f6d36df4ebb7c. La solución se incluirá en TensorFlow 2.11. También seleccionaremos este commit en TensorFlow 2.10.1 y 2.9.3, ya que también se ven afectados y aún se encuentran en el rango admitido. Sin embargo, no seleccionaremos este commit en TensorFlow 2.8.x, ya que depende del comportamiento propio que cambió entre 2.8 y 2.9.
