could not find valid device for node when call tf.acos

Hi @shiwenou ,
The tf.acos operation in tensorflow supports float and double data types but not an integer data types. When you pass an integer type tensor to tf.acos, it raises an error because there is no valid device registered for that operation with integer data types.
Here i am providing gist for your reference. Please go through it once.
Thank you!

Thanks for the answer. I found that in higher versions of tf it will warn that abs does not support integer type tensor. It's just that the version I'm using is too low.
Thank you!
