问题 I've built a small machine learning project that classifies music based on genre for my project, and I'm serving the feature extraction function through a REST API - flask-restful hosted on Heroku. The function takes in an audio file and returns extracted features such as MFCC.

Now, I've tried two different libraries

如何在Heroku上快速度的创建一个项目

由 守給你的承諾、 提交于 2020-03-07 09:54:39
Heroku是用git来管理项目的，另外还要用到ssh来登录，这两个工具请自行安装。 要用Heroku，当然就要安装它了。 ＄ sudo gem install heroku 先要生成一个公钥，使用命令: $ ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/home/user/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/user/.ssh/id_rsa. Your public key has been saved in /home/user/.ssh/id_rsa.pub. The key fingerprint is: a6:88:0a:bb:74:70:c6:e0:d5:49:65:e3:04:d5:6c:3e user@workstation.local 把公钥加入到Heroku $ heroku keys:add Uploading ssh public key /home/user/.ssh/id_rsa.pub

如何清空Heroku数据库

由 笑着哭i 提交于 2020-03-07 09:53:04
我正在研究Heroku上的Ruby on Rails 3 webapp。 如何清空数据库？ #1楼 我联系了Heroku支持，他们确认这是最新宝石的一个错误（我正在使用heroku-2.26.2） 查理 - 我们知道'heroku'宝石的这个问题并正在努力修复它。 如果你想跟进，这就是问题 - https://github.com/heroku/heroku/issues/356 降级到'heroku'宝石的早期版本应该会有所帮助。 我今天大部分时间都在使用v2.25.0而没有问题。 使用以下命令降级： gem uninstall heroku gem install heroku --version 2.25.0 如果您已经安装了多个gem，则可能会出现以下情况： Select gem to uninstall: 1. heroku-2.25.0 2. heroku-2.26.2 3. All versions 只需卸载＃2并重新运行该命令即可。 喜悦！ #2楼 我总是用单行'heroku pg：reset DATABASE'做到这一点。 #3楼 现在它与heroku不同。 尝试：heroku pg：reset DATABASE - 确认 #4楼 检查你的heroku版本。 我刚刚将我的更新到2.29.0，如下： heroku --version #=> heroku-gem/2
