AFAIU, this is only currently possible by repeatedly moving the computational window, which I think was slower (when I tested this for reading chunks for r.learn.ml2) than the performance from windowed reading in other libraries (e.g. GDAL/Rasterio).</li></ul><div><br class=""></div><div>Steve</div><div><br class=""><blockquote type="cite" class=""><div class="">On Sep 24, 2020, at 8:29 PM, Vaclav Petras <<a href="mailto:wenzeslaus@gmail.com" class="">wenzeslaus@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;" class="">Now would be a great time to do any large or small changes in the Python library.
