FigureCanvasAgg is non-interactive, and thus cannot be shown

FigureCanvasAgg是matplotlib中的一个类,它是非交互式的,无法直接在屏幕上显示图像。它主要用于将matplotlib绘制的图形输出为图片文件(如png、pdf等格式)。如果想要在交互式界面上展示图像,可以使用其他的FigureCanvas子类,例如FigureCanvasTkAgg、FigureCanvasQTAgg等。这些子类提供了与Tkinter、PyQt等GUI框架的集成,能够在交互式界面上显示matplotlib绘制的图像。

FigureCanvasAgg is non-interactive, and thus cannot be shown plt.show()
FigureCanvasAgg是Matplotlib库中的一个类,用于在非交互式环境中生成图形。它是Matplotlib的后端之一,负责将图形渲染为像素数组或图像文件。
当你调用plt.show()函数时,Matplotlib会尝试使用默认的后端来显示图形。然而,如果你正在使用的是非交互式的后端,比如FigureCanvasAgg,就会出现"FigureCanvasAgg is non-interactive, and thus cannot be shown"的错误。
这个错误的原因是FigureCanvasAgg不支持直接显示图形,因为它是为了在非交互式环境中生成图像而设计的。如果你想在交互式环境中显示图形,可以考虑使用其他后端,比如TkAgg或QtAgg。
What is muti-head attention?
Multi-head attention is a key component in the transformer architecture used for natural language processing tasks. It allows the model to jointly attend to different positions of the input sequence with different learned attention functions.
In multi-head attention, the input sequence is first projected into several smaller-dimensional representations, also known as heads. Each head then computes an attention function in parallel to capture different types of dependencies between the input tokens. The outputs of all the heads are concatenated and projected back into the original dimension to obtain the final output.
By using multiple attention heads, the transformer model can capture a richer set of dependencies and improve its ability to model complex relationships between the input tokens. It has been shown to achieve state-of-the-art performance on a range of natural language processing tasks, such as machine translation and language modeling.
