Hence…","summary":"In eager mode, TensorFlow versions before 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 do not set the session state. Calling `tf.raw_ops.GetSessionHandle` or `tf.raw_ops.GetSessionHandleV2` therefore triggers a null pointer dereference, because `ctx->session_state()` returns `nullptr` and the code dereferences it immediately, causing a segmentation fault.","solution":"Fixed in commit 9a133d73ae4b4664d22bd1aa6d654fec13c52ee1, released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 or
