python SyntaxError： only named arguments may follow *expression

def f(x,y,z):
    return [x,y,z]
调用f的时候,传入的参数如果包含*()表达式的话需要将其后对应的参数名带上
如： f(2, *a, z=3)  使用f(2, *a, 3) 可能会报错

在使用Flask静态文件的时候，每次更新，发现CSS或是Js或者其他的文件不会更新

解决方法：（1）清理浏览器缓存（2）设置Flask框架中app的config默认参数

  from datetime import timedelta
  app = Flask(__name__)
  app.config['SEND_FILE_MAX_AGE_DEFAULT'] = timedelta(seconds=1) # 我们配置缓存最大时间

参考

import tensorflow as tf with tf.Session() as sess: with open('./quantized_model.pb', 'rb') as f: graph_def = tf.GraphDef() graph_def.ParseFromString(f.read()) print graph_def output = tf.import_graph_def(graph_def, return_elements=['out:0']) print(sess.run(output))

#numpy 多条件查找
np.where((log[:,1]==3) | (log[:,1]==4))
#或者
np.logical_or(log[:,1]==3 , log[:,1]==4)
