imgs_file = sys.argv[1] IndexError: list index out of range

这个错误是由于索引超出范围导致的。在这个例子中,`sys.argv`是一个包含命令行参数的列表,而`sys.argv`表示获取列表中索引为1的元素。然而,如果没有提供足够的命令行参数,那么列表的长度将小于2,因此访问索引为1的元素将导致`IndexError: list index out of range`错误。
为了解决这个问题,你可以检查`sys.argv`列表的长度,确保至少有两个元素,然后再访问索引为1的元素。你可以使用以下代码来实现:
```python
import sys
if len(sys.argv) >= 2:
imgs_file = sys.argv[1]
# 其他操作
else:
print("请提供足够的命令行参数")
```
这样,如果没有提供足够的命令行参数,你可以在代码中进行相应的处理,例如打印错误信息或提示用户提供正确的参数。

image_path = self.imgs_path[index] IndexError: list index out of range
This error occurs when you are trying to access an element in a list using an index that is out of range.
For example, if you have a list with 5 elements and you try to access the 6th element using index 5, you will get this error.
To fix this error, you need to make sure that your index is within the range of the list. You can check the length of the list using the `len()` function and adjust your index accordingly.
Another possible cause of this error is that the list is empty. In this case, you need to make sure that the list is properly initialized and contains the elements you are trying to access.
修改下面代码使其忽略标签并依次选择索引,读取对应的图像序列路径(imgs_path),函数通过调用 self.loader() 函数来加载图像并一起返回 def getitem(self, index): current_index = np.random.choice(range(0, self.num_samples)) imgs_path = self.imgseqs[current_index].split() current_imgs = [] current_imgs_path = imgs_path[:len(imgs_path) - 1] current_label_path = imgs_path[len(imgs_path) - 1] current_label = self.loader(current_label_path)
def getitem(self, index):
current_index = index % self.num_samples
imgs_path = self.imgseqs[current_index].split()
current_imgs = []
current_imgs_path = [path for path in imgs_path[:-1] if not path.startswith("<")]
for img_path in current_imgs_path:
current_img = self.loader(img_path)
current_imgs.append(current_img)
current_label_path = [path for path in imgs_path if path.startswith("<")][0][1:-1]
current_label = self.loader(current_label_path)
return current_imgs, current_label
