<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My GDAL installation procedure looks like:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Install python 3.11.4 from the official site<o:p></o:p></p>
<p class="MsoNormal">brew install gdal (this grabbed numpy v1.25, and a number of other pre-reqs, and installs 3.6.4)<o:p></o:p></p>
<p class="MsoNormal">python -m venv test_env<o:p></o:p></p>
<p class="MsoNormal">// activate test_env //<o:p></o:p></p>
<p class="MsoNormal">pip install numpy (installs v1.25)<o:p></o:p></p>
<p class="MsoNormal">pip install gdal==3.6.4 (brew does not yet house 3.7)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This appears to work fine at first. I can manipulate gdal datasets up until I use band.ReadAsArray(). Python throws an exception `cannot import name '_gdal_array' from 'osgeo`.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Should this have worked? Stack Overflow has a few instances of this problem and they all point to incorrect install orders, or various software environments interacting poorly. But I don’t think I’m making those mistakes.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What causes my head to spin is that, I installed rasterio, and the ‘read’ function works! It must be via a different mechanism, but I wasn’t able to follow the code architecture in Github to see how they pull it off.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any advice? Thanks --<o:p></o:p></p>
