SSLCertVerificationError错误
问题
执行python whisper_demo.py报错，报错如下：
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed:
self signed certificate in certificate chain (_ssl.c:997)
During handling of the above exception, another exception occurred:

解决方案
全局取消证书验证，不推荐在正式环境使用，在py代码中引入：
import ssl
ssl._create_default_https_context = ssl._create_unverified_context
完整的代码如下：
import whisper
import ssl
ssl._create_default_https_context = ssl._create_unverified_context
model = whisper.load_model(name="tiny", download_root="./model")
# load audio and pad/trim it to fit 30 seconds
audio = whisper.load_audio("./data/zh.wav")
audio = whisper.pad_or_trim(audio)
# make log-Mel spectrogram and move to the same device as the model
mel = whisper.log_mel_spectrogram(audio).to(model.device)
# detect the spoken language
_, probs = model.detect_language(mel)
print(f"Detected language: {max(probs, key=probs.get)}")
# decode the audio
# options = whisper.DecodingOptions()
options = whisper.DecodingOptions(fp16 = False)
result = whisper.decode(model, mel, options)
# print the recognized text
print(result.text)
RuntimeError: "slow_conv2d_cpu" not implemented for 'Half'
问题
修复上面的问题后，继续执行whisper demo.py，报错如下：
result = whisper.decode(model, mel, options)

解决方案
因为默认是用的GPU模式，如果用CPU模式，是不支持float16的，需要设置为false。
I ran into the same error. I was able to resolve it after changing this line:
`options = whisper.DecodingOptions()`
to
`options = whisper.DecodingOptions(fp16 = False)`
