ทดสอบว่า python มองเห็น GPU ของเรา หรือไม่

กระทู้คำถาม

Python วิศวกรรมคอมพิวเตอร์ Open-source Software Microsoft Windows Operating System

ผมทดสอบโดยใช้ code ตามนี้ครับ

Gets to 99.25% test accuracy after 12 epochs
(there is still a lot of margin for parameter tuning).
16 seconds per epoch on a GRID K520 GPU.
