plt.savefig(os.path.join(args.basePath, 'loss&acc.png'), bbox_inches='tight')怎么让图片转化成svg格式

To save a plot as an SVG file instead of a PNG file using Matplotlib, you can modify your code as follows:

import os
import matplotlib.pyplot as plt

# ... your code for generating the plot ...

# Save the plot as an SVG file
plt.savefig(os.path.join(args.basePath, 'loss&acc.svg'), format='svg', bbox_inches='tight')

In the `savefig` function, the `format` argument specifies the file format to save the plot in. By setting it to `'svg'`, the plot will be saved as an SVG file. Additionally, the `bbox_inches='tight'` argument ensures that the saved plot does not contain any unnecessary whitespace.

Note that SVG files are vector graphics, which means that they are resolution-independent and can be scaled without losing quality. However, they may not be suitable for all purposes, and you should choose the appropriate file format based on your specific needs.
