python tensorflow windows environment to build experience

1. The need to install python3.7, anaconda package manager (similar to the java maven), tensorflow, pycharm development tools. Download the end of the annex.

2. Install tensorflow, start -Anaconda3-Anaconda3 Prompt. Open the console.

 

 

 

 conda create -n tensorflow python=3.5.2

Anaconda Home

 

 

3. Common package, Numpy: math library, Scipy: Senior module NumPy development,

pandas: import data, cleaning, processing, and output statistics,

Scikit-learn: specifically for machine learning Python open-source framework

Installation command
conda install XXX

Such as: conda install scipy

 

 

4. Open development tools pycharm.

 1 import numpy as np
 2 import matplotlib.pyplot as plt
 3 
 4 #心形线
 5 t = np.linspace(0, 2*np.pi, 100)
 6 x = 16 * np.sin(t) ** 3
 7 y = 13 * np.cos(t) - 5 * np.cos(2*t) - 2 * np.cos(3*t) - np.cos(4*t)
 8 plt.plot(x, y, 'r-', linewidth=2)
 9 plt.grid(True)
10 plt.show()

Results of the:

 

1 # 5.6 渐开线
2 t = np.linspace(0, 50, num=1000)
3 x = t*np.sin(t) + np.cos(t)
4 y = np.sin(t) - t*np.cos(t)
5 plt.plot(x, y, 'r-', linewidth=2)
6 plt.grid()
7 plt.show()
