我正在尝试将一本15小时长的有声读物分割成更短的1小时长的.mp3文件。下面是我为此创建的函数: from pydub import AudioSegment
import re, os, math
def process(fname, title):
head_dir = title + ' (split)'
if head_dir not in os.listdir():
os.mkdir(head_dir)
book = AudioSegment.from_file(fname)
seconds =
当triyng对带有numpy的数组进行right_shift时,我会得到一个错误:
以下是代码:
import numpy as np
a = np.ones((10, 10)) * 64
a.astype("int16")
b = a >> 2
我得到了
TypeError: ufunc 'right_shift' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the
我想在python中创建一个lmdb数据,其中标签不是标量,但每个标签都是(1,K)向量,K是类的数量。更具体地说,除了对应的类索引1之外,标签向量到处都是零。
我用python测试了以下代码:
with env.begin(write=True) as txn:
for i in range(N):
datum = caffe.proto.caffe_pb2.Datum()
datum.channels = X.shape[1]
datum.height = X.shape[2]
datum.width = X.shap
