For example, the standard softmax of(1,2,8)is approximately(0.001,0.002,0.997), which amounts to assigning almost all of the total unit weight in the result to the position of the vector's maximal element (of 8).
아무튼 커널에 의해서 캐싱된 내용을 어떻게 유지할 지 등에 대한 설정이 sysfs에 존재한다.
vm.vfs_cache_pressure This option controls the tendency of the kernel to reclaim the memory which is used for caching of directory and inode objects.
At the default value of vfs_cache_pressure=100 the kernel will attempt to reclaim dentries and inodes at a "fair" rate with respect to pagecache and swapcache reclaim. Decreasing vfs_cache_pressure causes the kernel to prefer to retain dentry and inode caches. When vfs_cache_pressure=0, the kernel will never reclaim dentries and inodes due to memory pressure and this can easily lead to out-of-memory conditions. Increasing vfs_cache_pressure beyond 100 causes the kernel to prefer to reclaim dentries and inodes.
With GlusterFS, many users with a lot of storage and many small files easily end up using a lot of RAM on the server side due to 'inode/dentry' caching, leading to decreased performance when the kernel keeps crawling through data-structures on a 40GB RAM system. Changing this value higher than 100 has helped many users to achieve fair caching and more responsiveness from the kernel.
is slower (by not having the app-data seed method), is not as extendable, cannot create virtual environments for arbitrarily installed python versions (and automatically discover these), is not upgrade-able via pip, does not have as rich programmatic API (describe virtual environments without creating them).
