我正在尝试在Python2.7(Ubuntu 16.04)中加载文件,并使用tqdm显示当前进度:
from tqdm import tqdm
import os
with open(filename, 'r') as f:
vectors = {}
tq = tqdm(f, total=os.path.getsize(filename))
for line in tq:
vals = line.rstrip().split(' ')
vectors[vals[0]] = np.array([float(x) for x in vals[1:]])
tq.update(len(line))
虽然不行,ETA太大了。它有点follows this example,但我试图像评论中所说的那样做。
答案 0 :(得分:1)
我发现密钥没有将文件对象作为“可迭代的”传递给对象。 tqdm的参数和手动管理更新:
from tqdm import tqdm
import os
filename = '/home/nate/something.txt'
with open(filename, 'r') as f:
# unit='B' and unit_scale just prettifies the bar a bit
tq = tqdm(total=os.path.getsize(filename), unit='B', unit_scale=True)
for line in f:
tq.update(len(line))
