Raspberry Pi Zero 2 W Development Flower Pot Pet
1. Materials required for hardware First, you need a Raspberry Pi board. Here we use the Raspberry Pi Zero 2 W. At the heart of the Raspberry Pi Zero 2 W is the RP3A0, a custom system-in-package designed by Raspberry Pi UK. Powered by a quad-core 1-bit ARM Cortex-A512 processor clocked at 53GHz and 2MB […]

[Distributed] tensorflow 1 distributed code practice and explanation; running 2 distributed worker threads on a single node
tensorflow.python.framework.errors_impl.UnknowError: Could not start gRPC server 1. tf distributed A computer = server = server is a node that contains multiple GPUs. First of all, the distributed method is to let the GPUs on multiple computers work together. Distributed work is divided into two parts, parameter server (ps) and worker. PS and worker look familiar, […]

Android data flow carnival: Channel and Flow
In the development of Android applications, handling asynchronous data streams is a common requirement. To better address these needs, Kotlin coroutines introduce Channel and Flow, which provide powerful tools to handle data flows, implement producer-consumer patterns, and build reactive applications. This article will take a deep dive into the internals of Channel and Flow, advanced […]
One article to quickly practice Kotlin coroutine and Flow
Foreword I don’t know if you all have the same feeling as me: even if you have carefully learned coroutines and Flow online, you have forgotten them after a while. Most of the reasons for this are actually due to our lack of actual combat. I don’t have access to coroutines and Flow at all […]
