无法使用 pandas 读取xlsb文件 [英] Unable to read xlsb file using pandas

问题描述

我正在尝试使用pandas的read_excel从本地读取xlsb文件，但出现错误. 我的代码:

I am trying to read an xlsb file from local using pandas' read_excel but I am getting error. My code:

import pandas as pd
df3 = pd.read_excel('a.xlsb', engine = 'pyxlsb')

错误:

    647 
    648         # could be a str, ExcelFile, Book, etc.

ValueError: Unknown engine: pyxlsb

它对于csv和xlsx文件正常工作.

It works fine for csv and xlsx files.

python版本:3.5.2
熊猫版本:0.24.2

python version: 3.5.2
pandas version: 0.24.2

推荐答案

进一步研究问题并参考@Datanovice的注释后，如果我更新到pandas v1.0，则对我有用. 我正在使用ubuntu 16.04，它可以自动将我的python更新到3.5，不再更新，并且python 3.6支持pandas v1.0.因此，即使使用最新版本进行更新，我也无法运行代码. 我们可以安装python 3.6并为此安装pandas v1.0.

After looking into the problem a bit more and referring to @Datanovice 's comment, it works for me if I update to pandas v1.0. I am using ubuntu 16.04 which can automatically update my python to 3.5, not any further and pandas v1.0 is supported from python 3.6. Hence, even after updating with the latest versions, I was not able to run the code. We can install python 3.6 and install pandas v1.0 for that.

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.6

使用pandas 3.6，我们只需将引擎作为pyxlsb传递给read_excel即可读取文件.

Using pandas 3.6, we can simply pass the engine as pyxlsb to read_excel to read the file.

import pandas as pd
df3 = pd.read_excel('a.xlsb', engine = 'pyxlsb')

在Ubuntu 16.04上安装python3.6的参考: https://askubuntu.com/questions/865554/how-do-i-install-python-3-6-using-apt-get
