AttributeError: 'builtin_function_or_method' object has no attribute 'requires_grad_'
时间: 2023-09-26 18:07:15 浏览: 322
This error message typically occurs when you try to call the `requires_grad_()` method on a built-in Python function or method. The `requires_grad_()` method is used in PyTorch to specify whether a tensor requires gradient computation during backpropagation.
To fix this error, make sure that you are calling the `requires_grad_()` method on a PyTorch tensor, and not on a Python built-in function or method. Double-check that you have properly defined and initialized your PyTorch tensors before calling this method on them.

AttributeError: 'builtin_function_or_method' object has no attribute
AttributeError通常表示对象没有特定的属性或方法。这可能是由于对象类型不正确或代码中的拼写错误等原因引起的。下面是两个例子,演示了AttributeError的不同情况:
1. 'builtin_function_or_method' object has no attribute 'randint'
```python
import random
print(random.randint(1, 10)) # 正确的调用方式
print(random.randit(1, 10)) # 错误的调用方式,应为randint而非randit
```
2. 'builtin_function_or_method' object has no attribute 'sleep'
```python
import time
time.sleep(1) # 正确的调用方式
time.slep(1) # 错误的调用方式,应为sleep而非slep
```
AttributeError: 'builtin_function_or_method' object has no attribute 'perf_counter'
这个错误提示是在使用'perf_counter'属性时发生的。根据引用\[1\]中的解决办法,这个错误通常是因为你在调用'perf_counter'属性之前没有正确导入相应的模块。请检查你的代码,确保你已经正确导入了包含'perf_counter'属性的模块。如果你没有导入正确的模块,你可以使用类似于'from time import perf_counter'的语句来导入所需的模块。这样,你就可以正确地使用'perf_counter'属性了。
