ImportError: DLL load failed while importing _multiarray_umath: 找不到指定的模块（pyinstaller打包的问题）

时间：2021-10-17 16:12:30

本人环境配置：

RTX3060

Win10

cuda11.1

Python3.8

Pytorch1.7.1

问题描述

本人需要将有导入torch包的python文件通过pyinstaller打包生成exe。

pyinstaller命令使用D参数，即生成一个dist文件夹，里面包含exe和需要调用的dll，命令行如下：

python -D your_python.py

显示结果如下：

最后的结果带有successfully就代表exe生成成功了。

打包显示成功，但是运行exe会报如下错误：
