感謝分享。賺到六千。

Python有用過卻沒學過，

撐很多年，為了發神經，看來要學了。

1.If you have Python 2 >=2.7.9 or Python 3 >=3.4 installed from python.org, you will already have pip and setuptools, but will need to upgrade to the latest version:

python -m pip install -U pip setuptools

2.pip install scipy

3.conda install scipy

4.function... 敘述列要縮排對齊......

5.pip install tensorflow / pip install --upgrade tensorflow (命令列要系統管理員或Anaconda prompt)

6.Spyder
import tensorflow as tf
hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))
a = tf.constant(10)
b = tf.constant(20)
print(sess.run(a*b))

7.一天內深度發神經網路碰完成
