Python 3.6.5(64位)上的GDAL [英] GDAL on Python 3.6.5 (64-bit)

问题描述

过去一个小时，我一直在尝试在Windows上的Python 3.6.5(64位)上安装GDAL，但没有任何效果.

I've been trying to install GDAL on Python 3.6.5 (64-bit) on Windows for the past hour, and nothing works.

我已经访问了一些关于SO的问题，观看了有关YT的视频，但是这些问题都不适合我的情况(这没什么特别的.)

I've visited some questions on SO, watched a video on YT, but none of them applies to my situation (which there's nothing special about it).

有人可以提供循序渐进的解决方案，最好是经过测试的解决方案，这样我才能弄清楚我到底在做错什么?

Can someone provide a step-by-step solution, preferably a tested one, so I can figure out what exactly I'm doing wrong?

如有必要，我愿意提供任何操作系统设置信息/屏幕截图.

I'm willing provide any OS setting info/screenshot if necessary.

更新:我正在尝试安装GDAL，以将TIF(16位)文件转换为JPG或PNG.尽管我设法用第二种方法(第二次尝试)安装了GDAL，但是我却不能使用gdal_translate.因此，并非每个GDAL lib/version都对我有用.

Update: I'm trying to install GDAL to convert TIF (16-bit) files to JPG or PNG. Although I managed to install GDAL with the second method (at second try), I could not use gdal_translate. So not every GDAL lib/version works for me.

第一种方法:

• GDAL 2.3.0 (建议

• 依赖项:
  • libgdal(2.3.0或更高版本)和头文件(gdal-devel)(在哪里/如何获得此文件?)
  • numpy (1.0.0或更高版本)和头文件(numpy-devel)
  • Dependencies:
    • libgdal (2.3.0 or greater) and header files (gdal-devel) (where/how do I get this?)
    • numpy (1.0.0 or greater) and header files (numpy-devel)

    需要"GDAL Windows二进制文件". Google搜索使我想到了这一点: DownloadingGdalBinaries – GDAL

    Requires "GDAL Windows Binaries". A Google search led me to this: DownloadingGdalBinaries – GDAL

    • 尝试过 GISInternals -> 和"GDAL-2.3.0.win-amd64-py3.4.msi". (最新版本适用于python 3.4吗?)
    • 已将"gdal-203-1911-x64-core.msi"安装到"C:\Program Files\GDAL".

    • 在自述文件中说

    • Tried GISInternals -> Releases -> release-1911-x64-gdal-2-3-0-mapserver-7-0-7
    • Downloaded "gdal-203-1911-x64-core.msi" and "GDAL-2.3.0.win-amd64-py3.4.msi". (The latest release is for python 3.4?)
    • Installed "gdal-203-1911-x64-core.msi" to "C:\Program Files\GDAL".

    • In README, it says

    将安装目录bin文件夹添加到系统PATH ...

    Add the installation directory bin folder to your system PATH...

    C:\ gdalwin32-1.7 \ bin

    C:\gdalwin32-1.7\bin

    "C:\Program Files\GDAL"中没有"bin"文件夹. GDAL目录中的文件夹:"csharp"，"gdal-data"，"gdalplugins"，"license"，"projlib".那...?

    There is no "bin" folder in "C:\Program Files\GDAL". Folders in GDAL dir: "csharp", "gdal-data", "gdalplugins", "license", "projlib". So ...?

    我什至不打算完成此操作，因为它似乎已经过时了(我已经通过电子邮件将其描述告知了作者，因此希望它可以解决).我遵循了其他步骤，但是显然没有用.随时尝试.

    I'm not even going to finish this because it seems outdated (I've emailed it's author about the description, so I hope it gets fixed). I followed the other steps, but it didn't work, obviously. Feel free to try it out.

    第二种方法:

    • Gohlke Pythonlibs (建议

    • 下载的"GDAL-2.2.4-cp36-cp36m-win_amd64.whl"

    • 在页面顶部，它说(我可能在第一次尝试中就错过了)

    • Downloaded "GDAL-2.2.4-cp36-cp36m-win_amd64.whl"

    • At the top of the page, it says (I probably missed this in the first try)

    许多二进制文件依赖于numpy-1.14 + mkl和...

    Many binaries depend on numpy-1.14+mkl and ...

    所以我已经下载了"numpy-1.14.4+mkl-cp36-cp36m-win_amd64.whl"(在同一页面中)

    So I've downloaded "numpy-1.14.4+mkl-cp36-cp36m-win_amd64.whl" (it's in the same page)

    已安装它们:

    pip install numpy-1.14.4+mkl-cp36-cp36m-win_amd64.whl

    pip install GDAL-2.2.4-cp36-cp36m-win_amd64.whl

    并且有效(尽管使用gdal_translate时我丢失了dll(ogr_FileGDB)错误，所以不使用它)

    and it worked (though I'm getting missing dll (ogr_FileGDB) error when using gdal_translate, so not using this)

    我将使用尝试的方法对此进行更新.

    I'll be updating this with the methods I've tried.

    推荐答案

    conda-forge的预构建GDAL版本在Windows 64位python 3.6.5上非常有用

    The prebuild GDAL version from conda-forge works great on windows 64 bit python 3.6.5

    您可以安装 Anaconda (或安装Anaconda后，我通常使用Anaconda提示符，而不是常规的Windows命令提示符.

    After installing Anaconda, I usually use the Anaconda prompt instead of the regular windows command prompt.

    (可选)如果您想在特定环境中隔离它

    我建议在anaconda中使用环境，因此创建一些环境 像这样

    I would recomend using environments with anaconda so create some environment like this

    conda create --name gdal_env python=3.6.5

    activate gdal_env

    环境不是必需的，因此您可以跳过此步骤并继续安装gdal.

    Environments are not required, so you can skip this step and continue to installing gdal.

    安装gdal

    conda install -c conda-forge gdal

    我发现conda-forge是(到目前为止)在Windows上安装GDAL的最简单方法.如果由于某种原因您需要使用另一个python发行版，我也发现预编译二进制文件也可以从这里正常工作本指南

    I have found conda-forge to be the (by far) easiest way to install GDAL on windows. If for some reason you are required to use another python distribution, i have found the prebuild binaries from here to work fine too https://www.lfd.uci.edu/~gohlke/pythonlibs/ if you follow this guide
