[PYTHON] Deep Learning with Shogi AI on Mac and Google Colab

Book "Deep Learning Learned with Shogi AI" by Tadao Yamaoka Original source code https://github.com/TadaoYamaoka/python-dlshogi.git

Purpose

Run "Deep Learning with Shogi AI" on iMac and Google Colab. Build the basic environment on the iMac and use the GPU of Google Colab only when learning.

environment

iMac iMac 2020 27inch default model 3.1GHz 6-core 10th generation Intel Core i5 processor Up to 4.5GHz when using Turbo Boost 8GB 2,666MHz DDR4 memory 256GB SSD storage Radeon Pro 5300 (with 4GB GDDR6 memory) OS : Catalina Python: 3.8.2 and 2.7 pre-installed. This time I used 3.8.2. Google Colab Python 3.6.9

Summary of results
