我正在尝试移除频谱图的图例(我想要一个244x244像素的图像)
我已经尝试过在matplotlib图中移除图例,但它的效果非常奇怪 - 我得到了结果和一个异常!
(我正在使用Google Colab)
import numpy as np
import matplotlib.pyplot as plt
%matplotlib inline
import moviepy.editor as mpy
import youtube_dl
## downloading the video
ydl_opts = {
'format': 'bestaudio/best',
'postprocessors': [{
'key': 'FFmpegExtractAudio',
'preferredcodec': 'wav',
'preferredquality': '192',
}],
}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
ydl.download(['https://www.youtube.com/watch?v=5pIpVK3Gecg'])
## selecting the audio clip from 17oth second to 180th second and saving it in talk.wav
from moviepy.video.io.ffmpeg_tools import ffmpeg_extract_subclip
ffmpeg_extract_subclip("Tyler, The Creator - 'IGOR,' Odd Future and Scoring a"
"Number 1 Album _ Apple Music-5pIpVK3Gecg.wav", 170,
180, targetname="talk.wav")
talk = mpy.AudioFileClip('talk.wav')
# switching axis off
plt.axis('off')
sample_rate = talk.fps
NFFT = sample_rate /25
audio_data = talk.to_soundarray()
#trying to get a 244 x 244 pixel image
fig, ax = plt.subplots(nrows=1, ncols=1, figsize=(2.44, 2.44), dpi=100.)
ax.axis('off')
spectrum, freqs, time, im = ax.specgram(audio_data.mean(axis=1), NFFT=NFFT, pad_to=4096,
Fs=sample_rate, noverlap=512, mode='magnitude', )
########## the problem lies here ##########
ax.get_legend.remove()
##trying to save stuff to drive but this doesnt run because of the exception
fig.colorbar(im)
fig.savefig('specto.png')
import os
print( os.getcwd() )
print( os.listdir('specto.png') )
from google.colab import files
files.download( "specto.png" )
有什么方法可以解决这个问题吗?
ax.get_legend().remove()
时,它似乎能够工作但会出现错误 - https://imgur.com/a/Ss4NFki 有没有一种方法可以在不出现错误的情况下使其正常工作? - Pradyumna
