However, it’s absolutely clear that Theano (I’m going to test also Tensorflow) should be the best choice if you want to implement deep learning algorithms (in particular if you have a good GPU). <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 11 0 R 17 0 R] /MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>>

You should clear the execution_times array between the Theano and Numpy runs. Sorry, your blog cannot share posts by email. 1 0 obj
As a programming environment, I’ve used Python 2.7 (Anaconda distribution) and Jupyter. Then run the project again, and it should work same way as under Python 3.4 (or higher) Installing Theano: For installing theano, the best approach is to use anaconda that you used earlier to install scipy. However, the calculations are correct (confirmed also by the plots). Theano is a Python library and optimizing compiler for manipulating and evaluating mathematical expressions, especially matrix-valued ones. As it is, the Theano execution times are included in the Numpy average. x��X[o��~��0�V��U#A�4�-R`�ic�8H���e[�#��vs��ɑ�����ƺp8�G�R��mS-�Y���&MS�V��O����'ӗ�rrS,��h�M}~�~��d�LOO&�$��æ������j�mƜ��~�ul�;=lIwY{�����H&��o�'A#j����P���ED��B����V�}�|�����|y}�D��b��<

Differences Between Theano vs Tensorflow. %����
Theano is an open source project primarily developed by the Montreal Institute for Learning Algorithms at the Université … Final results are: Using gpu device 0: GeForce GTX 960M (CNMeM is enabled with initial size: 20.0% of memory, CuDNN 3007) Theano: Result: 2.000000 Average execution time: 39690 (us) Numpy: Result: 2.000001 Average execution time: 158240 (us) So, Numpy is on average 300% slower than Theano (with GPU support). In Theano, computations are expressed using a NumPy-esque syntax and compiled to run efficiently on either CPU or GPU architectures. \�}+���68:Z��9�u+�ku|j���t$R�P� }Q���)�B�ʢ&+?$R��3 �s��(�ސ"H���E_�LF�`��@p����S��c�ƣyW������p��K�����/m�w�}Ѱ[˕D��NJ`��4+ ,���D3��H]�t�U�

But TensorFlow is comparatively easier yo use as it provides a lot of Monitoring and Debugging Tools. For example, here is the radial wavefunction corresponding to n = 3 and l = 1 for Carbon (Z = 6) SymPy is great at this. All Rights Reserved. Just add a, execution_times = [], after the Theano results are printed and before the Numpy calculations are started. NumPy-Esque syntax has been used to implement this library … Copyright © Giuseppe Bonaccorso. Final Verdict: Theano vs TensorFlow On a Concluding Note, it can be said that both APIs have a similar Interface . In this benchmark, I’ve used a Windows 10 Pro 64 Bit computer with Intel Core i7 6700HQ 2.60 GHz with 32 Gb RAM and NVIDIA GeForce GTX 960M. It is used to being the feature of artificial intelligence by making the use of python. Thanks Jim. Haven't found any general-purpose theano vs numpy benchmarks, but in the article there is comparison of neural networks and theano is expected to give much better speed than numpy/torch(c++)/matlab, specially it is fast on GPU Theano may be defined as the library that belongs to python and facilitates the application development by optimizing the compiler for the evaluation of the mathematical expression and also their manipulations. Here the diagrams: The spikes should be due to CPU overload, multitasking or memory swapping. Post was not sent - check your email addresses! Indeed it was a typo when copying from the Jupyter notebook. Then using pip install the numpy and scipy as you did for the Python 2.7 environment. The task is very simple, integrating this expression (simple but effective): The code I’ve written is this (without matplotlib functions and float32 numbers, in order to use the GPU): So, Numpy is on average 300% slower than Theano (with GPU support). <>
