python

问题 I have plotted some data with Python and tried to change the ticks with FuncFormatter . Now I want to change the segmentation into round numbers. I also want minor ticks in the same formation, in my case it would be a 1/x segmentation. I want the scaling to spread. The pictures will help you to imagine my issue. import numpy as np import matplotlib.pyplot as plt import matplotlib.ticker as tick x = np.array([805.92055,978.82006,564.88627,813.70311,605.73361,263.27184,169.40317]) y = np.array(

问题 How can I compare a Tensorflow string tensor to a python string type. I tried something like this if(tf.constant("neg",tf.string) in key): a=True key here, is a tf.string. I want to see if 'neg' is in the key tensor. 回答1: Unfortunately, currently you cannot. Please ask this on TF github in issues section. 来源： https://stackoverflow.com/questions/35946810/compare-tf-string-and-python-string

问题 Why am I seeing different result on GPU compare to sequential CPU? import numpy from numba import cuda from functools import reduce A = (numpy.arange(100, dtype=numpy.float64)) + 1 cuda.reduce(lambda a, b: a + b * 20)(A) # result 12952749821.0 reduce(lambda a, b: a + b * 20, A) # result 100981.0 import numba numba.__version__ # '0.34.0+5.g1762237' Similar behavior happens when using Java Stream API to parallelize reduction on CPU: int n = 10; float inputArray[] = new float[n]; ArrayList<Float

问题 I am using AWS lambda functions for a few months now. so far I have cached the connection in the lambda function memory to reuse. After reading about AWS rds proxy recently, I am trying to utilize the connection pool for the lambda functions(Runtime python3.7). so to test the way rds proxy works with lambda functions, I created two functions with runtime node12 and python3.7, the behaviours was this. 1. node12 function => When I run this function, it pools two connection in the proxy and
