from torch._C import * (ImportError: DLL 加载失败：找不到指定的模块。)

Question

我正在使用 Windows 10 和 Python 3.6.10 到 conda 4.8.3。

我对 Python 相当陌生，并且正在虚拟环境中使用 PyInstaller 从我制作的深度学习工具中创建可执行文件。 该程序打开一个tkinter window 并对用户提供的数据运行arcgis.learn函数。 Arcgis.learn 需要fastai 、 PyTorch 、 torchvision和scikit-image作为其依赖项。 我使用conda install -c esri -c fastai -c pytorch arcgis=1.8.1 scikit-image=0.15.0 pillow=6.2.2 libtiff=4.0.10 fastai=1.0.60 pytorch=1.4.0 torchvision=0.5.0 tensorflow-gpu=2.1.0 --no-pin了它们conda install -c esri -c fastai -c pytorch arcgis=1.8.1 scikit-image=0.15.0 pillow=6.2.2 libtiff=4.0.10 fastai=1.0.60 pytorch=1.4.0 torchvision=0.5.0 tensorflow-gpu=2.1.0 --no-pin 。 PyInstaller 创建可执行文件，尽管有许多警告，但在调用任何 arcgis.learn function 后失败，并出现以下错误：

File "site-packages\torch\__init__.py", line 81, in <module>
ImportError: DLL load failed: The specified module could not be found.

第 81 行from torch._C import * 。 当我在 Jupyter Notebook 中运行代码时，所有包和模块都正确导入并按预期工作。 我尝试了以下解决方案：

• 确保 PYTHONPATH 指向 [PythonRoot]、[PythonRoot]\Library\bin、[PythonRoot]\Scripts、[PythonRoot]\bin 和 %SYSTEMROOT%
• 在 .spec 文件中附加隐藏导入
• 重新安装 pytorch
• 安装我已经安装的 VC 2017 Redist
• 这篇文章提到了另一个名为 torch 的文件夹，但我看了之后一无所获。

我不确定 go 从这里到哪里，所以任何帮助将不胜感激。 PyInstaller的反馈如下，很多库都找不到。 值得注意的是，torch_python.dll 丢失了。

Answer 1

解决了。

只需将 missing.dll 文件的目录附加到 my.spec 文件中的 pathex 即可修复。 就我而言，路径是'C:/User/Users/Anaconda3/envs/myenv/Lib/site-packages/torch/lib' 。 提供tensorflow和zmq文件的路径也删除了它们各自的警告。

可悲的是，我仍然遇到其他导入错误，因此似乎避免了一个更大的问题。
