【问题描述】:
我有一个名为 batch_df 的 df,我在 df 中添加了“as_percentage”。如果 hours 是 Nan,则将 as_percentage 设置为 0。代码在 PyCharm 中运行良好,但当我在终端上运行时,出现此错误:请帮助!
Traceback(最近一次调用最后一次):
文件“/Users/vic_ong/dev/resource-management/generateBatch.py”,第 166 行,在 主要()
文件“/Users/vic_ong/dev/resource-management/generateBatch.py”,第 51 行,在 main
batch_df.loc[pd.isna(batch_df['hours']) == False, 'as_percentage'] = 0 AttributeError: 'module' 对象没有属性 'isna'
编辑 -- 我的代码如下所示:
#!/usr/bin/env python2
import lib
import pandas as pd
import datetime
import os
pd.set_option('expand_frame_repr', False)
# get directories
batchInputDir = '/Users/vic_ong/dev/resource-management/data/input/batchUpload'
def main():
# start timer
start_time = datetime.datetime.now()
# walk into every csv file in batchUpload and concatenate them into one df
list_ = []
for root, dirs, files in os.walk(batchInputDir):
for file in files:
if file.endswith('.csv'):
df = pd.read_csv(os.path.join(batchInputDir, file), index_col=None, header=0)
list_.append(df)
batch_df = pd.concat(list_)
batch_df = batch_df.dropna(how='all')
batch_df.reset_index(drop=True, inplace=True)
# clean data frame
# rename to standardized column names
batch_df.rename(columns={'Resource Name': 'name',
'Hours': 'hours'},
inplace=True)
# determine if value given was a percentage
batch_df['as_percentage'] = 1
batch_df.loc[pd.isna(batch_df['hours']) == False, 'as_percentage'] = 0
print batch_df.head
if __name__ == '__main__':
main()
batch_df 样本:
name hours as_percentage
vic Nan 1
vic1 Nan 1
【问题讨论】:
-
您需要发布其余代码。
pd是什么?从您的 sn-p 中看不出来。是你重命名的panda模块吗? -
更新你的熊猫。它可能已经过时了。
-
@robobrobro 是的,这是我重命名的 pandas 模块。我刚刚添加了我的其余代码。
-
我不认识pandas,但你的意思是打电话给
pd.isnan吗?
