我无法解决问题。我使用的是 python 3.7。请提出一个可能的解决方案。

标签： python openexr

【解决方案1】：

我遇到了同样的问题。经过一番研究，我在 GitHub 上发现了一些与此相关的问题，例如[1]、[2]、[3]。显然需要先在系统上安装 openexr C++ 库，然后才能安装 Python 包。

在 Ubuntu 上，您可以简单地执行 sudo apt-get install libopenexr-dev，但对于 Windows，您似乎需要自己从 this repo 编译它。

但是，对于某些 Python 包here，有一个 非官方 Windows 二进制文件列表，其中包括 OpenEXR 并为我工作。就我而言，我只是下载了相应的版本并安装了它：

python -m pip install OpenEXR‑1.3.2‑cp36‑cp36m‑win_amd64.whl
