TF_VersionHello World test- The first commit refers to the rather simplistic hello world program for the C API and not in general for Tensorflow. This is present here. This Hello world test works!

Graph, Tensor & Session based proper TF Hello World test
- The better hello world test is to be able to program a real "Hello World!" TF program. This would involve declaring a string as a Tensorflow constant and then run a session to print the Tensor in a graph. As Python is still the best client for TF, this would look something like this in Python:
import tensorflow as tf with tf.Session() as sess: print(sess.run(tf.constant("Hello World!")))
OUTPUT: "Hello World!"This requires the creation of C bindings capable of creating a new graph, constant string tensors, new operations, creating a session and then running it. All the code has been done so far for running string tensors in sessions (after graphs and operations have been created) in the NIF. This works as well.
-
Before doing anything, on the command line type
make(You will see some warnings-- ignore them, they have been taken care of) to compile the C NIF code insrc. -
