Hi: SCP whenever I try to define an ROI in the training input I get the error: "Error [65]". Any idea what is causing this?

Error [65]: Error, extent of vector too large or attribute table error." I uninstalled and reinstalled QGIS 3.26.2 but I still get the error. Any idea what is causing this?

The error message you're encountering, "Error [65]: Error, extent of vector too large or attribute table error," typically indicates an issue with working with vector data (like shapefiles or other spatial formats) in a Geographic Information System (GIS) software like QGIS. This error can occur for various reasons. Here are a few things you can try to troubleshoot and resolve the issue:

Data Corruption: The vector dataset you are trying to open might be corrupted. Try opening a different dataset to see if the issue persists. If the problem is specific to one dataset, it's likely that the data itself is corrupted. You might want to obtain a fresh copy of the dataset.

File Size or Complexity: The error could be related to the size or complexity of the vector dataset. If the dataset is too large, it might exceed the memory capacity of your system, leading to this error. Try working with a smaller subset of the data or optimizing the dataset before loading it into QGIS.

Attribute Table Issues: Sometimes, errors in the attribute table of a vector dataset can cause issues. You could try repairing or rebuilding the attribute table using tools available in QGIS or external software.

Software Version Compatibility: Ensure that the version of QGIS you are using is compatible with your operating system and the dataset format you're working with. While you mentioned using QGIS 3.26.2, it's important to verify that this version is indeed available and supported, as the most recent version I'm aware of is QGIS 3.22.

Memory Allocation: If your system's memory is constrained, it might struggle to handle large datasets. You can adjust the memory allocation settings in QGIS to allocate more memory for processing. Go to Settings > Options > System in QGIS and adjust the "Maximum feature count" and "Maximum editing buffer size" settings accordingly.

Update or Reinstall: Although you mentioned reinstalling QGIS, make sure that you have the latest stable version installed. Sometimes, bugs are fixed in newer releases that might resolve the issue you're facing.

Check Log Messages: QGIS usually provides log messages that can give more detailed information about the error. Check the QGIS log window or log file for more insights into what might be causing the error.

Extensions or Plugins: If you have any extensions or plugins installed in QGIS, they might be contributing to the issue. Try disabling them and see if the error persists.

Operating System Issues: Occasionally, operating system updates or changes can affect the functioning of software. Ensure that your operating system is up-to-date and doesn't have any compatibility issues with QGIS.

If none of these steps resolve the issue, you might want to seek assistance from the QGIS community forums or support channels. Providing specific details about the dataset you're working with and any additional error messages you encounter can help others provide more targeted assistance.
