AttributeError: 'numpy.ndarray' object has no attribute 'counts'
时间: 2023-11-09 18:07:21 浏览: 68
这个错误是因为你尝试在一个 NumPy 数组上访问名为 'counts' 的属性,但该数组并没有这个属性。通常情况下,NumPy 数组没有名为 'counts' 的属性。可能是你在使用 NumPy 数组的时候出现了错误,或者可能是你想要访问数组中的某个其他属性。请确保你正确地使用了 NumPy 数组并且没有拼写错误。
如果你能提供更多的上下文或者代码片段,我可以帮助你更详细地解决这个问题。

修改错误AttributeError: 'numpy.ndarray' object has no attribute 'count'
出现`'numpy.ndarray' object has no attribute 'contiguous'`这个错误是因为你在PyTorch中尝试对numpy数组调用`contiguous`属性,但这个属性是PyTorch tensor特有的,而不是numpy数组所具有的。当你从numpy转换到PyTorch tensor时,通常需要确保数据连续(即内存布局连续),以便于高效计算。
以下是修正错误的步骤[^1]:
1. 首先,你需要将numpy数组转换为PyTorch tensor:
```python
import torch
x = np_array # 假设x是一个numpy数组
x = torch.from_numpy(x)
```
2. 然后,如果你的numpy数组是不连续的,可以使用`contiguous()`方法使其连续:
```python
x = x.contiguous()
```
如果你遇到`AttributeError: 'numpy.ndarray' object has no attribute 'count'`,则表示你试图在numpy数组上使用`count`方法,但numpy没有这个属性。`count`是用于计数元素出现次数的,对于numpy,你可以使用`np.count_nonzero()` 或者 `np.unique(x, return_counts=True)`来实现相同功能。
AttributeError: module 'numpy' has no attribute 'histogram_bin_edges'
This error occurs when trying to use the function `histogram_bin_edges` from the `numpy` module, but it is not found.
This function was introduced in NumPy version 1.17.0, so it is possible that you are using an older version of NumPy that does not have this function.
To resolve this error, you can try updating your version of NumPy to the latest version, or you can use an alternative method for computing histogram bin edges. One alternative is to use `numpy.histogram` to compute the histogram and then use the `bins` output to get the bin edges. For example:
```
import numpy as np
data = np.random.normal(size=1000)
hist, bin_edges = np.histogram(data, bins='auto')
```
This will compute a histogram of the `data` array using the 'auto' algorithm for choosing the number of bins, and return the histogram counts in `hist` and the corresponding bin edges in `bin_edges`.
