python 3.74 运行import numpy as np 报错lib\site-packages\numpy\__init__.py
这个异常通常发生在读取文本文件时,文件中包含了特殊字符或二进制数据,导致`ValueError: embedded null character`异常。
在你的代码中,出现了这个异常的原因可能是文件路径中包含了一个空字符。请尝试将文件路径中的双反斜杠(`\`)更改为正斜杠(`/`),或者在路径字符串前面添加一个`r`以将其视为原始字符串。
例如,将文件路径中的双反斜杠(`\`)更改为正斜杠(`/`):
```python
with open('E:/radar_dataset_astyx-main/dataset_astyx_demo/radar_hires1/000000.txt', 'r') as file:
```
或者,在路径字符串前面添加一个`r`以将其视为原始字符串:
```python
with open(r'E:\radar_dataset_astyx-main\dataset_astyx_demo\radar_hires1\000000.txt', 'r') as file:
```
请注意,如果文件路径中确实包含特殊字符或二进制数据,你需要检查文件内容并确保它符合所期望的格式。
希望这能帮到你!如果你还有其他问题,请随时提问。
