kandi X-RAY | tilelive Summary

tilelive is a JavaScript library typically used in Data Preparation applications. tilelive has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

:warning: tilelive and related mapbox-owned tilelive plugins are not actively maintained. Please open a new issue to check with the project maintainers before beginning work on new features. Tilelive is designed for streaming map tiles from sources (like custom geographic data formats) to sinks (destinations, like file systems) by providing a consistent API. This repository enables the interaction between sources and sinks and is meant to be used in tandem with at least one Tilelive plugin. Tilelive plugins (modules) follow a consistent architecture (defined in API.md) and implement the logic for generating and reading map tiles from a source or putting map tiles to a destination, or both. An example of a plugin that implements both reading (can be a source) and writing (can be a sink) is tilelive-s3. An example use case for tilelive is creating vector tiles from a geojson file and putting them to Amazon S3. This can be accomplished by using tilelive-omnivore as the source and using tilelive-s3 as the sink. Tilelive omnivore performs special operations for generating map tiles (using mapnik), whereas tilelive-s3 is able to properly connect to Amazon S3 for putting tiles in their proper location. The Tilelive module performs all of the getting and putting within tilelive.copy. See Usage for more details on the tilelive module API.

            Prepare for Binary Masks used for the image segmentation
            Asked 2022-Mar-30 at 08:33

            I am trying to prepare the masks for image segmentation with Pytorch. I have three questions about data preparation.

            1. What is the appropriate data format to save the binary mask in general? PNG? JPEG?

            2. Is the mask size needed to be set square such as (224x224), not a rectangle such as (224x448)?

            3. Is the mask value fixed when the size is converted from rectangle to square?

            For example, the original mask image size is (600x900), which is binary [0,1]. However, when I applied

            1. PNG, because it is lossless by design.
            2. It depends. More convenient is to use standard resolution, (224x224), I would start with that.
            3. Use resize without interpolation transforms.Resize((300, 300), interpolation=InterpolationMode.NEAREST)

            Yolov5 object detection training
            Asked 2022-Mar-25 at 04:06

            Please i need you help concerning my yolov5 training process for object detection!

            I try to train my object detection model yolov5 for detecting small object ( scratch). For labelling my images i used roboflow, where i applied some data augmentation and some pre-processing that roboflow offers as a services. when i finish the pre-processing step and the data augmentation roboflow gives the choice for different output format, in my case it is yolov5 pytorch, and roboflow does everything for me splitting the data into training validation and test. Hence, Everything was set up as it should be for my data preparation and i got at the end the folder with data.yaml and the images with its labels, in data.yaml i put the path of my training and validation sets as i saw in the GitHub tutorial for yolov5. I followed the steps very carefully tought.

            The problem is when the training start i get nan in the obj and box column as you can see in the picture bellow, that i don't know the reason why, can someone relate to that or give me any clue to find the solution please, it's my first project in computer vision.

            This is what i get when the training process starts

            This the last message error when the training finish

            I think the problem comes maybe from here but i don't know how to fix it, i used the code of yolov5 team as it's in the tuto

            The training continue without any problem but the map and precision remains 0 all the process !!

I think that the problem was in my personnel laptop environment maybe the version of pytorch i was using '1.10.0+cu113', or something else ! If you have any advices to set up my environnement for yolov5 properly i would be happy to take from you guys. many Thanks again to @alexheat

            scatter plot color bar does not look right
            Asked 2022-Mar-24 at 22:20

            I have written my code to create a scatter plot with a color bar on the right. But the color bar does not look right, in the sense that the color is too light to be mapped to the actual color used in the plot. I am not sure what is missing or wrong here. But I am hoping to get something similar to what's shown here: https://medium.com/@juliansteam/what-bert-topic-modelling-reveal-about-the-2021-unrest-in-south-africa-d0d15629a9b4 (about in the middle of the page)

            The colorbar uses the given alpha=.3. In the scatterplot, many dots with the same color are superimposed, causing them to look brighter than a single dot.

            One way to tackle this, is to create a ScalarMappable object to be used by the colorbar, taking the colormap and the norm of the scatter plot (but not its alpha). Note that simply changing the alpha of the scatter object (scatter.set_alpha(1)) would also change the plot itself.

            Why do we different results?

            Supplying inputs in either the same batch, or separate batches, can make a difference if the model includes dependencies between different elements of the batch. By far the most common source in current deep learning models is batch normalization. As you mentioned, the discriminator does include batchnorm, so this is likely the reason for different behaviors. Here is an example. Using single numbers and a batch size of 4:

            This is an interesting situation. It seems that maybe you can sidestep some of the manual process/thread handling and utilize something like multiprocessing's Pool. I made an example based on some other data initializing code I had. This delegates creating test data and inserting it for each of 10 "devices" to a pool of 3 processes. One caveat that seems necessary is to dispose of the engine before it is shared across fork(), ie. before the Pool tasks are created, this is mentioned here: engine-disposal

            The way you specify the parameter is via a dictionary that maps the name of the estimator/transformer and name of the parameter you want to change to the parameters you want to try. If you have a pipeline or a pipeline of pipelines, the name is the names of all its parents combined with a double underscore. So for your case, it looks like

            Weights are initialized when the layers are defined (before fit). It does not re-initialize weights afterward - even if you call fit multiple times.

            To show this is the case, I plotted the decision boundary at regular training epochs (by calling fit and then predict):
