I have to use tf.function(jit_compile=true), but it seems contradicts with tf.py_function, sending out error message No registered ‘EagerPyFunc’ OpKernel for XLA_GPU_JIT devices compatible with node {{node EagerPyFunc}}){{node EagerPyFunc}}
import tensorflow as tf
import numpy as np

def my_numpy_func(x):  # This function must be numpy function, because it involves lots of scipy operations
  # tf.function
  return np.sinh(x)

# @tf.function(input_signature=[tf.TensorSpec(None, tf.float32)]) # ok, but I have to use jit_compile parameter
@tf.function(input_signature=[tf.TensorSpec(None, tf.float32)],jit_compile=True) # error because of jit_compile parameter
def tf_function(input):
  y = tf.py_function(my_numpy_func, [input], tf.float32)
  return y * y

a = tf_function(tf.constant(1.))
print(a)
