AttributeError: 'builtin_function_or_method' object has no attribute 'requires_grad_'
时间: 2023-09-26 10:07:15 浏览: 73
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 'py'
根据提供的引用内容,你遇到了一个AttributeError: 'builtin_function_or_method' object has no attribute 'py'的错误。这个错误通常发生在你尝试访问一个对象没有的属性或方法时。
以下是一个演示如何出现这个错误的例子:
```python
import math
print(math.py) # 这里尝试访问math模块中不存在的属性'py'
```
当你运行这段代码时,会出现AttributeError: 'builtin_function_or_method' object has no attribute 'py'的错误,因为math模块中没有名为'py'的属性。
为了解决这个错误,你需要确保你正在访问正确的属性或方法。你可以查看相关文档或使用dir()函数来查看对象的属性和方法。
