detectron2,手把手教你训练mask_rcnn

青春壹個敷衍的年華 提交于 2020-01-08 02:05:22
弄了好几个月,现在终于能训练自己的数据了。 首先 cuda 10.2 PyTorch 1.3.1 labelme 3.18.0 安装 PyTorch 和 labelme 直接 anaconda 下面 pip 就好,之所以不用 conda ,是因为使用 conda 下 PyTorch 不能使用 cuda , pip 会帮你安装 cudatoolkit=10.2 。 1、使用labelme整理数据 1.1 使用下面代码重命名图片文件,显得专业点。 # -*- coding: utf-8 -*- """ Spyder Editor HGH """ import os import cv2 path_img = r '/images' dirs = os . listdir ( path_img ) os . chdir ( path_img ) try : os . mkdir ( 'rename' ) except : pass count = 0 for img in dirs : img = cv2 . imread ( img , 1 ) Str = "%06d" % count path = os . path . join ( 'rename' , Str + '.jpg' ) cv2 . imwrite ( path , img ) count += 1 可以得 打开

插曲 之前已发布了一次了。在编写和发布的过程中一直有一个BUG困扰着我。最后被我找到了,只能暂时避开这个BUG重新发布一篇了。之前那篇就被我删掉了,浏览和收藏的也没了。 那个问题我也记录下来了: https://blog.51cto.com/steed/2071264 Web的三个层次 网页设计思路是把网页分成三个层次,即:结构层(HTML)、表示层(CSS)、行为层(Javascript)。 形象的比喻,先是HTML捏了一个人,然后CSS则是给人穿上衣服,最后通过JS让人动起来。 Web服务的本质 对于所有的Web应用,本质上其实就是一个socket服务端,用户的浏览器其实就是一个socket客户端。用户向服务器发送一个请求。然后服务器响应,将数据和格式发回给客户端,然后断开这个连接。客户端收到返回的数据后,通过浏览器将数据按照一定的格式呈现出来。整个过程就是一个socket的短连接。 下面是一个服务端的python代码,实现一个简单的Hello World: import socket def handle_request(conn): data = conn.recv(1024) # 接收数据,随便收到啥我们都回复Hello World conn.send('HTTP/1.1 200 OK\r\n\r\n'.encode('utf-8')) # 这是什么暂时不需要知道

Winforms: system.windows.forms.label text displayed as text in label

守給你的承諾、 提交于 2020-01-07 14:19:59
问题 I have created a simple program. One of the functions is that it counts clicks, and when the program finishes, a label is displayed with some text and the number of clicks. The code works, but the problem is that the label displays extra text, like this: system.windows.forms.label text Stevec is set to count clicks. Lable konec already contains text, and in this case I just want to add the extra sentence with the number of clicks. konec.Text = konec + " Kliknil si: " + Stevec.ToString() + "

I would like to add another label (alread did in the project) and se it so some information will appear here depending on what item was chosen in the table view. Just

Add Label with Textbox at design time

走远了吗. 提交于 2020-01-07 05:30:48
问题 I am creating a project using VS.NET (C#) with many forms that contain textboxes and associated labels. I have created the association through an exposed property I created for the textbox which contains the label name. The problem is that each time I add a textbox at design-time I have to add a label and then enter the label name into the property of the textbox. I would much rather do this dynamically at design-time when I create the textbox, much like the old VB textbox add. I have been

“Command failed due to signal: Segmentation fault: 11” - What is the issue?

跟風遠走 提交于 2020-01-07 05:05:15
问题 I did some research and still have no idea what is causing this error in my code (well, I know what is causing it, but I don't know why...) Essentially, I retrieve an array, results , from Parse Cloud Code. Then I send it to ViewController2 to print out a section of the array in the format of a UILabel . When I do this I get the compiler error. This is really confusing me! Please note that result , the array that I retrieve contains both Strings and Boolean values which is why I made it

Auto-Label in scatter plot using matlab

好久不见. 提交于 2020-01-07 05:01:11
问题 so in continuation of my problem a while ago, having this suggested program: %// Input A =[ 2 1 5 1 3 10 1 -2 5 0 5 25 5 0 25 1 1 2 -1 -1 2] [unqcol3,unqidx,allidx] = unique(A(:,3),'stable') counts = sum(bsxfun(@eq,A(:,3),unqcol3.'),1) %//' out =[A(unqidx,:) counts(:)] scatter(out(:,3), out(:,4)) so it will generate an array and a plot like this: a b d counts 2 1 5 2 1 3 10 1 0 5 25 2 1 1 2 2 d vs. counts but i want to put (a,b) as a labels on each scatter point, so this the plot out put i

adding labels to candlestick chart in matplotlib

蹲街弑〆低调 提交于 2020-01-07 04:20:13
问题 I'm trying to add a series (composed of a list of [1,2,0,....]) to a candlestick chart I produced with matplotlib, but cannot work out how to include those labels for each specific candle in the graph. Basically I'd like to produce a chart like this one: (source: linnsoft.com) with the labels with the numbers (my signal series) just over or below each candles. Is there any way I can reach that? Don't know if it helps, but my series are of the pandas DataFrame kind... 回答1: Here's an example
