<p>我是python编程的新手，但在尝试从RAVDESS数据集wav文件绘制光谱图时，我一直在与这些错误作斗争。这就是代码</p>
<pre><code>`for file in range(0 , len(listOfFiles) , 1):
windows_size = 20
sample_rate , samples = wavfile.read(listOfFiles[file])
nperseg = int(round(20 * sample_rate / 1e3))
frequencies , times, spectrogram = signal.spectrogram(samples, sample_rate)
plt.pcolormesh(times, frequencies, spectrogram)
plt.imshow(spectrogram)
plt.ylabel('Frequency [Hz]')
plt.xlabel('Time [sec]')
plt.show()`
</code></pre>
<p>以下是错误</p>
<pre><code><ipython-input-16-dc119f345487>:14: WavFileWarning: Chunk (non-data) not understood, skipping it.
sample_rate , samples = wavfile.read(listOfFiles[file])
<ipython-input-16-dc119f345487>:14: WavFileWarning: Incomplete chunk ID: b'\x00', ignoring it.
sample_rate , samples = wavfile.read(listOfFiles[file])
<ipython-input-16-dc119f345487>:17: MatplotlibDeprecationWarning: shading='flat' when X and Y have the same dimensions as C is deprecated since 3.3. Either specify the corners of the quadrilaterals with X and Y, or pass shading='auto', 'nearest' or 'gouraud', or set rcParams['pcolor.shading']. This will become an error two minor releases later.
plt.pcolormesh(times, frequencies, spectrogram)
</code></pre>
<p>很抱歉，我不能更好地解释错误，但我是新手，任何形式的帮助都会令人惊讶</p>
