解决pytorch报错ImportError: numpy.core.multiarray failed to import
项目场景
最近在学pytorch
,先用官网提供的conda
命令安装了一下:
conda install pytorch torchvision cudatoolkit=10.2 -c pytorch
然后按照官网的方法测试是否安装成功,能不能正常使用:
import torch
x = torch.rand(5, 3)
print(x)
若能正常打印出x
的值,则说明可以正常使用,否则反之。
问题描述
代码运行报错:ImportError: numpy.core.multiarray failed to import
D:\miniconda3\envs\pytorch\lib\site-packages\numpy\__init__.py:138: UserWarning: mkl-service package failed to import, therefore Intel(R) MKL
initialization ensuring its correct out-of-the box operation under condition when Gnu OpenMP had already been loaded by Python process is not
from . import _distributor_init
Traceback (most recent call last):

from torch._C import *
ImportError: numpy.core.multiarray failed to import
原因分析
python
环境自带一个numpy
,会与安装的pytorch
带的numpy
版本间发生冲突。
解决方案
- 先卸载
numpy
conda uninstall numpy
- 再重装
numpy
conda install numpy
最终结果
按照上述方案处理后正常打印出了x
的值:
tensor([[0.8338, 0.1541, 0.0379],
[0.4348, 0.0145, 0.3586],
[0.4098, 0.2363, 0.5405],
[0.7372, 0.7418, 0.3703],
[0.5668, 0.9512, 0.8041]])
我们再来看看GPU
驱动和CUDA
是否能用:
import torch
print(torch.cuda.is_available())
控制台打印显示True
,则说明能正常使用。
