tensorflow slim inception_v3 model error - tensorflow

Question

I am trying to use the tensorflow inception_v3 model for a transfer learning project.I get the following error on building the model.
TypeError: Expected int32, got list containing Tensors of type '_Message' instead.
The same error does not arise on using the same script for inception_v1 model.
The models are imported from slim.nets
Running on CPU
Tensorflow version : 0.12.1
Script
import tensorflow as tf
slim = tf.contrib.slim
import models.inception_v3 as inception_v3
print("initializing model")
inputs=tf.placeholder(tf.float32, shape=[32,299,299,3])
with slim.arg_scope(inception_v3.inception_v3_arg_scope()):
logits,endpoints = inception_v3.inception_v3(inputs, num_classes=1001, is_training=False)
trainable_vars=tf.get_collection(tf.GraphKeys.TRAINABLE_VARIABLES)
for tvars in trainable_vars:
print tvars.name

Found my mistake, i was importing the model from https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/slim/python/slim/nets whereas the updated models are at https://github.com/tensorflow/models/tree/master/slim/nets.
Still haven't understood why there are two different repositories for the same classes.Must be a valid reason.
