[mcj]Python未绑定方法
“未绑定方法”是Python中的一种调用方式，指的是当Python中使用类来调用类的方法时，由于此时调用方法的不是对象，而是类本身，相当于没有调用者。此时Python不会自动为方法的第一个参数self绑定参数值。因此程序必须显式地为第一个参 […]
[mcj]Python中调用静态方法、类方法、未绑定方法时自动绑定对比
使用对象调用未绑定方法的话，Python会执行自动绑定 使用类调用未绑定方法的话，Python不会执行自动绑定 使用类或对象调用静态方法的话，Python都不会进行自动绑定 使用类或对象调用类方法的话，Python都会进行自动绑定。 一般在 […]
Python中的进度条使用–tqdm
主要是想要查看Python处理的进度，好在Python有很多库，这次使用的是tqdm。 tqdm就能非常完美的支持和解决这些问题，可以实时输出处理进度而且占用的CPU资源非常少，支持windows、Linux、mac等系统，支持循环处理、多 […]

[mcj]Pytorch单GPU改为多GPU训练
原来是：
|
1 2 3 |
use_cuda = (args.gpu >= 0) and torch.cuda.is_available() device = torch.device("cuda" if use_cuda else "cpu") model = model.to(device) |
这时用的是单GPU，我们需要改为多GPU，需要在model.to(device)之前加一句
|
1 |
model = nn.DataParallel(model, device_ids = [0, 1]) |
即可。 […]
[mcj]RuntimeError: Input type (torch.cuda.FloatTensor) and weight type (torch.FloatTensor) should be the same
使用pytorch的时候，想要对网络进行可视化，结果报错为： RuntimeError: Input type (torch.cuda.FloatTensor) and weight type (torch.FloatTensor) sho […]
[mcj]Jupyter Notebook从任意IP访问以及指定IP访问
好长时间不用jupyter notebook了，最近用的时候，本地127.0.0.1可以打开，但是从远程访问死活不行，本机的iptables删了，ufw也关了，都不好使，后来才发现，jupyter在启动的时候是可以设置访问来源IP的。 设置 […]
