Hello there,

Python version: 3.9.12  
wradlib version: 1.17.0

I tried to reinstall the latest version of wradlib using conda in my virtual environment. It got successfully installed. When I was trying to read the data set I was getting the following error. I understand this is being caused because of the installation problem of gdal package in the virtual environment. When I run “conda list” in the shell it displays list of packages installed. Here I can see gdal(version 3.4.1) installed. But when I run in python and tried to import the module gdal, I get this error.(ModuleNotFoundError: No module named ‘gdal’)

```auto
comp = []
for f in os.listdir(src_path):
    comp_ = wrl.io.open_radolan_dataset(src_path+f)
    comp.append(comp_)

```

```auto
for f in os.listdir(src_path):
    comp_ = wrl.io.open_radolan_dataset(src_path+f)
    comp.append(comp_)

You tried to access function/module/attribute 'SpatialReference'
from module 'osgeo.osr'.
This module is optional right now in wradlib.
You need to separately install this dependency.
Please refer to https://docs.wradlib.org/en/stable/installation.html#optional-dependencies
for further instructions.

Hi @SandeepAllampalli,

can you try to import just GDAL in your environment?

```python
from osgeo import osr

```

Hello SandeepAllampalli,  
I also faced the Same issue follow the following

1. Make sure you installed Gdal latest version after enabling your environment as  
`conda install gdal`
2. Then Execute  
`conda upgrade numpy`
3. Restart Kernal

The problem that I found is that Installing Gdal will downgrade the NumPy version so after installation of Gdal you should upgrade numpy

Hi @adithiyrnair ,

That really worked like a gem. Thank you for the help.
