-- There are a few distinct differences between Tensorflow and Pytorch when it comes to data compuation.

-**How "Graph" is defined in each framework?**
-
-#**TensorFlow:** 
-
-- Static graph.
-
-- Once define a computational graph and excute the same graph repeatedly.
-
-- Pros: 
-
-    (1) Optimizes the graph upfront and makes better distributed computation.
-    
-    (2) Repeated computation does not cause additional computational cost.
-
-
-- Cons: 
-
-    (1) Difficult to perform different computation for each data point.
-    
-    (2) The structure becomes more complicated and harder to debug than dynamic graph. 
-
-
-#**PyTorch:** 
-
-- Dynamic graph.
-
-- Does not define a graph in advance. Every forward pass makes a new computational graph.
-
-- Pros: 
-
-    (1) Debugging is easier than static graph.
-    
-    (2) Keep the whole structure concise and intuitive. 
-    
-    (3) For each data point and time different computation can be performed.
-    
-    
-- Cons: 
-
-    (1) Repetitive computation can lead to slower computation speed. 
-    
-    (2) Difficult to distribute the work load in the beginning of training.

 # **01 Tensor**
 
 Both TensorFlow and PyTorch  are based on the concept "Tensor".
