PermissionDeniedError

[Malathi15]

After completed my training I tried to convert my checkpoints to .model file

I use this code for convert my checkpoint(.data/.meta/.index) to .model file

 w1 = tf.Variable(tf.truncated_normal(shape=[10]), name='w1')
w2 = tf.Variable(tf.truncated_normal(shape=[20]), name='w2')
tf.add_to_collection('vars', w1)
tf.add_to_collection('vars', w2)
saver = tf.train.Saver()
sess = tf.Session()
sess.run(tf.global_variables_initializer())
saver.save(sess, '/models/c3d_ucf_model-4999')

I got this error
