Docker - apt-get安装失败(Docker - apt-get install fail)
我有一个非常容易的码头 - 撰写/码头同步脚本：

I have a pretty easy docker-compose/docker-sync script:
docker-compose-dev.yml
# this is our development docker-compose building on top of the production docker-compose, just mounting # the sync image - not redefining anything else version: "2" services: apache: volumes: - ./docker-config/vhost:/etc/apache2/sites-enabled/000-default.conf - jettsw53-sync:/var/www/html:nocopy # nocopy is important # that the important thing volumes: jettsw53-sync: external: truedocker-compose.yml

version: "2" options: verbose: true syncs: jettsw53-sync: # tip: add -sync and you keep consistent names as a convention src: './src' sync_excludes: ['.git', 'var/cache/*']When I start this setup, I get this error when running apt-get install:

您可以在http://www.cs.berkeley.edu/~malik/papers/SM-ncut.pdf （等式11）的第4页上下文中看到该公式。 在那篇论文中，他们使用F作为强度，我假设你有。因为你的强度是标量，你只想取其差异的平方。
您想要计算一个权重矩阵，用于计算A中任何条目与A中任何其他条目的亲和力。因为您的A有25个条目，所以您的权重矩阵将为25x25。
因为你只关心亮度这很容易：
len = length(A(:)); W = zeros(len); for i = 1:len for j = 1:len W(i,j) = (A(i) - A(j))^2; end end现在，如果你想查看A（1,1）和A（1,2）之间的权重，你可以这样做：
i = sub2ind(size(A), 1, 1) j = sub2ind(size(A), 1, 2) W(i, j)但是如果你设置r = 1（根据NCuts公式）那么你可能想要这样的东西：
sigma= 10; r = 1; A = magic(3); siz = size(A); len = length(A(:)); W = zeros(len); for i = 1:len for j = 1:len [xi,yi] = ind2sub(siz,i); [xj,yj] = ind2sub(siz,j); if((xi-xj)^2 + (yi-yj)^2) > r^2 W(i,j) = 0; else W(i,j) = exp(-(A(i) - A(j))^2 / sigma^2); end end end A11 = sub2ind(siz, 1, 1) A12 = sub2ind(siz, 1, 2) W(A11, A12)You can see that formula in context on page 4 of http://www.cs.berkeley.edu/~malik/papers/SM-ncut.pdf (equation 11). In that paper they use F for intensity where I assume you have I. Since your intensities are scalars, you just want to take the square of their differences.
You want to calculate a weight matrix that calculates the affinity of any entry in A to any other entry in A. Because your A has 25 entries, your weight matrix will be 25x25.
Since you are only worried about the brightness this is easy:
len = length(A(:)); W = zeros(len); for i = 1:len for j = 1:len W(i,j) = (A(i) - A(j))^2; end endNow if you want to look up the weight between A(1,1) and A(1,2) you can do it like this:
i = sub2ind(size(A), 1, 1) j = sub2ind(size(A), 1, 2) W(i, j)But if you set r=1 (according to the NCuts formula) then you might want something like this:
sigma= 10; r = 1; A = magic(3); siz = size(A); len = length(A(:)); W = zeros(len); for i = 1:len for j = 1:len [xi,yi] = ind2sub(siz,i); [xj,yj] = ind2sub(siz,j); if((xi-xj)^2 + (yi-yj)^2) > r^2 W(i,j) = 0; else W(i,j) = exp(-(A(i) - A(j))^2 / sigma^2); end end end A11 = sub2ind(siz, 1, 1) A12 = sub2ind(siz, 1, 2) W(A11, A12)
