在Udacity完成AI课程时,我在转学习部分遇到了这个错误.这是似乎导致麻烦的代码:

import torch
from torch import nn
from torch import optim
import torch.nn.functional as F
from torchvision import datasets, transforms, models

data_dir = 'filename'

# TODO: Define transforms for the training data and testing data
train_transforms= transforms.Compose([transforms.Resize((224,224)), transforms.Normalize(mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225]), transforms.ToTensor()])
test_transforms= transforms.Compose([transforms.Resize((224,224)), transforms.Normalize(mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225]), transforms.ToTensor()])

# Pass transforms in here, then run the next cell to see how the transforms look
train_data = datasets.ImageFolder(data_dir + '/train', transform=train_transforms)
test_data = datasets.ImageFolder(data_dir + '/test', …

我正在Udemy学习React 16课程.我们正在使用Codepen在课程中创建我们的第一个React应用程序.虽然教师能够在视频中呈现组件,但我遵循他的代码并且它不会呈现.这是HTML,CSS和JS代码:

HTML:

<div class="person">
  <h1>Your name</h1>
  <p1>Manu</p1>
</div>

CSS:

.person {
  margin:10px;
  box-shadow:2px 2px #ccc;
  border: 1px solid #eee;
  padding: 20px;
  width: 200px;
  display: inline-block;
}

JavaScript的:

function Person(){
  return(
    <div className="person">
      <h1>Your name</h1>
      <p1>Tristan</p1>
    </div>
  );
}

ReactDOM.render(<Person/>, document.querySelector('#p1'));
