问题描述

我已经使用whl发行版安装了fiona ..但是在导入时出现以下错误:

i have installed fiona using whl distributions.. but while importing i am getting following error :

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

     10 from fiona.ogrext import Session, WritingSession
     11 from fiona.ogrext import (

有人可以提出解决方案吗?

can anyone suggest a solution.?

推荐答案

当我安装fiona并尝试导入它时，我也遇到了一些麻烦.我收到了这样的消息

I had also some troubles when i installed fiona and tried to import it. I had this kind of message

>>> import fiona
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "D:\Software\Ingenieria\Anaconda2\lib\site-packages\fiona\__init__.py", l
ine 77, in <module>
    from fiona.collection import Collection, BytesCollection, vsi_path
  File "D:\Software\Ingenieria\Anaconda2\lib\site-packages\fiona\collection.py",
 line 9, in <module>
    from fiona.ogrext import Iterator, ItemsIterator, KeysIterator
ImportError: DLL load failed: The specified module could not be found.

最后它对我有什么作用?

How did it work for me at the end?

• 我通过链接安装了GDAL 2.2.4和Fiona发行版
• 然后，我检查我的计算机是否具有适用于python的c ++编译器(此处链接有关您可能需要安装的信息).在某些论坛问题中，我读到GDAL需要此编译器才能工作.
• 然后，我将Osgeo文件夹路径(有fiona的dll)添加到我的路径环境变量中，这是我PC上的一些图片打印屏幕2 打印屏幕2

• I installed the distributions GDAL 2.2.4 and Fiona from this link
• Then i checked if my computer has a c++ compiler for python (here link with some information about which one you may need to install). In some forum questions i read that GDAL need this compiler to be able to work.
• Then i added the Osgeo folder path (there are the dlls for fiona) to my path environment variable, some pics from my pc Print screen 1 Print screen 2

执行完这些步骤后，fiona不再存在任何问题.最初，我使用的是GDAL 1.1.4版，但从未与该版本一起使用.您可以先尝试使用版本1，如果它不起作用，则安装版本2.2.4

After doing those steps i never had any more problems with fiona. At first, i was using the GDAL version 1.1.4 but it never worked with this one. You can try first with the version one, and if it doesn´t work then install the version 2.2.4
