Issue 1:
I am running the BoostedTreesClassifier tutorial (https://www.tensorflow.org/tutorials/estimator/boosted_trees) on tf2.0

During the training call:

Train model.

linear_est.train(train_input_fn, max_steps=100)

a "double free or corruption (!prev)" is logged and the python process crashes

TF 2.0.0 (pip installed)

Ubuntu 19.04

python 3.7

cuda 10.0.130

GPU: RTX 2080 Ti

Other tensorflow components (ie keras) work fine

Issue 2:
import tensorflow as tf
