通过最大化可见输入数据的可能性来学习 RBM 的这些参数。 如果我们用θ = [W; b; c]表示组合的参数集,并且有一组T训练输入数据点,则在 RBM 中,我们尝试使似然函数最大化: [外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-i18aIGwg-1681654125431)(https://gitcode.net/apachecn/...
开始以为错误是由于传递的最后一个参数由i改为seeds引起,google后发现元组、列表、字符串类型都是pickleable的。 错误是传递的db类型变为thread.lock造成的,而之前的db没有进行数据库操作故没有连接数据库。 于是,在db进行数据库操作后断开数据库连接后再传入Pool就好了。
In order to get rid of the ‘valueerror unsupported pickle protocol 5’ error, you can check out some tips: Use the highest pickle protocol if possible. Check your Python version first. With pickle5, you don’t need to think of compatibility problems. ...
