在Python中使用Geopandas读取shapefile时出错

Question

I am trying to read a shapefile using geopandas, for which I used gp.read_file

import geopandas as gp
fl="M:/rathore/vic_5km/L2_data/L2_data/DAMSELFISH_distributions.shp"
data=gp.read_file(fl)

I am getting the following error: TypeError: invalid path: UnparsedPath(path='M:/rathore/vic_5km/L2_data/L2_data/DAMSELFISH_distributions.shp')

The traceback to the problem is:

----> 1 data=gp.read_file(fl)

There is some problem with fiona I guess but I do not have much idea about. I have installed fiona 1.8.6 and geopandas 0.5.0 version installed in my system. I am using python 2.7

Answer 1

It says that path is invalid. I would try to replace comma in your path:

before:

fl="M:/rathore/vic_5km/L2_data/L2_data/DAMSELFISH_distributions,shp"

after:

fl="M:/rathore/vic_5km/L2_data/L2_data/DAMSELFISH_distributions.shp"

Answer 2

I think it has nothing to do with version of fiona and geopandas. Can you find the path of the file through your command prompt/terminal and use the same for reading the file like below

fl="/Users/xxxx/Downloads/Data/DAMSELFISH_distributions.shp"

Hope this helps

Answer 3

First, isinstance(your_path, ((str,), Path)) is evaluated to False in fiona\\collection.pyc , which is strange.

Also, those lines in fiona/ init .py module should take care of the case where your path is a pathlib.Path object, but it apparently don't... I'm not sure, it may be an issue with fiona.

I still think the problem come from the parse_path(path) method of fiona.

Here are some things you should try:

1. If M: is a shared folder on a local network, try replacing 'M:/...' by the UNC path (ex: "//local/folder/path/to/file")
2. If you use an IDE (like Pycharm, Eclipse or VsCode), add a breakpoint on your third line, use the debugger and go deep down until you reach the parse_data method. then look at what your path looks. If you don't use an IDE, consider to install one...
3. If you can, try copying the shapefile on the same drive that your python script, and check if the errors still raises.
