如何解决RuntimeError: [在 CPUAllocator.cpp:65 处强制失败] DefaultCPUAllocator：无法分配内存
这是我试图运行的 python 脚本：
import easyocr
reader = easyocr.Reader(['en'])
result = reader.readtext('test.jpg')
print(result)
我在我的电脑上试过了，它有效。 但是，在 Raspberry Pi 上尝试时却没有。 我使用的是虚拟环境。
- numpy 版本：1.20.2
- easyocr 版本：1.3.0.1
- 火炬版本：1.7.0a0+e85d494
- Torchvision 版本：0.8.0a0+45f960c
- Python 版本：3.7.3
这是我通过终端运行它时得到的：
CUDA not available - defaulting to CPU. Note: This module is much faster with a GPU.
