My dashboard has a 2 x 2 graph layout with one checklist overlaid on each graph. Each graph requires a unique ID, to be live-updated via callbacks. These IDs are generated in a loop (e.g., graph-BMW, graph-MB, etc.). Similarly, each checklist has a unique ID generated via the same loop (e.g., checklist-BMW, c…
How to continue training with checkpoints using object_detector.EfficientDetLite4Spec tensorflow lite
Preciously I have set my EfficientDetLite4 model “grad_checkpoint=true” in config.yaml. And it had successfully generated some checkpoints. However, I can’t figure out how to use these checkpoints when I want to continue training based on them. Every time I train the model it just start from…
Is overlay how=’difference’ supposed to operate differently from geopandas 0.9 vs 0.10?
I was using the difference set operation for a different problem, but I would get an empty geodataframe or None type when replacing a polygon with the difference in my geodataframe. I found it to be a result of having non-intersecting polygons and doing the difference set-operation. I was wondering is this no…
Accessing M-values associated to LINESTRING M and MULTILINESTRING M geometries
How can I access a line geometry’s multiple M-values? Consider that the line geometry in question can be either a LINESTRING M or MULTILINESTRING M geometry that was created using osgeo/ogr. Here’s a small reproducible example: In the example above, the line_geom and mline_geom objects are success…
Can’t replace an array inside a tuple with another array of same size – Python
I have a list of tuples: I want to replace the second np.array of the first tuple with an array of the same length but filled with zeros: I have tried the following: But I get the: Any idea how to complete the replacement process ? Answer Tuples are immutable in Python, you cannot change values stored in it. …

Gradient exploding problem in a graph neural network
I have a gradient exploding problem which I couldn’t solve after trying for several days. I implemented a custom message passing graph neural network in TensorFlow which is used to predict a continuous value from graph data. Each graph is associated with one target value. Each node of a graph is represe…
