Question

我正在尝试在Visual Studio 2019中配置chromedriver

我知道这很简单，但是我无法启动chromedriver

我已经使用Visual Studio 2019并在此路径中使用了chromedriver：

\ Visual Studio 2019 \ Python脚本\ Python 3.7（64位）

但是当我尝试执行此代码时：

# Count the number of True per week per ID
out = df.groupby(["ID", pd.Grouper(key='Date', freq='1W')])["Received"] \
        .sum() \
        .to_frame() \
        .reset_index() \
        .rename(columns={"Received": "Count"})
print(out)
#     ID                      Date  Count
# 0  000 2018-01-07 00:00:00+00:00    2.0
# 1  000 2018-01-14 00:00:00+00:00    2.0
# 2  000 2018-01-28 00:00:00+00:00    1.0
# 3  111 2018-01-07 00:00:00+00:00    3.0


# Fill missing date ranges
def fill_date_range(df):
    dates = pd.date_range(df.Date.min(), df.Date.max(), freq="1W")
    return df.set_index("Date") \
             .reindex(dates)[['Count']] \
             .fillna(0)

# Fill missing date range             
out = out.groupby(by="ID").apply(fill_date_range) \
        .reset_index()  \
        .rename(columns={"level_1": "Date"})
print(out)
#     ID                      Date  Count
# 0  000 2018-01-07 00:00:00+00:00    2.0
# 1  000 2018-01-14 00:00:00+00:00    2.0
# 2  000 2018-01-21 00:00:00+00:00    0.0
# 3  000 2018-01-28 00:00:00+00:00    1.0
# 4  111 2018-01-07 00:00:00+00:00    3.0

# Add date range interval as string
format = '%Y-%m-%d %H:%M:%S'
out["Date_expected"] = out.Date.dt.strftime(format) + " - " + (out.Date + pd.Timedelta(weeks=-1)).dt.strftime(format)
print(out)
#     ID                      Date  Count                              Date_expected
# 0  000 2018-01-07 00:00:00+00:00    2.0  2018-01-07 00:00:00 - 2017-12-31 00:00:00
# 1  000 2018-01-14 00:00:00+00:00    2.0  2018-01-14 00:00:00 - 2018-01-07 00:00:00
# 2  000 2018-01-21 00:00:00+00:00    0.0  2018-01-21 00:00:00 - 2018-01-14 00:00:00
# 3  000 2018-01-28 00:00:00+00:00    1.0  2018-01-28 00:00:00 - 2018-01-21 00:00:00
# 4  111 2018-01-07 00:00:00+00:00    3.0  2018-01-07 00:00:00 - 2017-12-31 00:00:00

我得到：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Chrome() 
driver.get("http://www.python.org")

我不知道为什么python找不到它

任何帮助将不胜感激

谢谢

即使我将其放置在PATH中也找不到Chromedriver
