为什么报错
这是有关pandas的作业：Step 1. Go to https://www.kaggle.com/openfoodfacts/world-food-facts/data
Step 2. Download the dataset to your computer and unzip it.
In :
import pandas as pd
import numpy as np
Step 3. Use the tsv file and assign it to a dataframe called food¶
In :
food = pd.read_csv('~/Desktop/en.openfoodfacts.org.products.tsv', sep='\t')
运行到这步后就出错了，报错如下：
IOErrorTraceback (most recent call last)
<ipython-input-13-489f4e8333cb> in <module>()
----> 1 food = pd.read_csv('~/Desktop/en.openfoodfacts.org.products.tsv', sep='\t')
