ImportError: DataFrame.to_markdown requires tabulate

ImportError: DataFrame.to_markdown requires tabulate

$ python -c "import pandas as pd; df = pd.DataFrame({'a':[1]}); df.to_markdown()"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: Missing optional dependency 'tabulate' - required to use DataFrame.to_markdown

Why this happens

DataFrame.to_markdown produces a Markdown-formatted table using the third-party tabulate library. If that optional dependency isn’t installed, pandas raises ImportError.

Fix

Install tabulate with pip install tabulate. After installation df.to_markdown() will work. Use pip install 'pandas[all]' or the specific package to install many optional I/O dependencies.

Wrong code

import pandas as pd
df = pd.DataFrame({'a':[1]})
# Fails if `tabulate` is not installed
df.to_markdown()

Fixed code

python -m pip install tabulate

import pandas as pd
df = pd.DataFrame({'a':[1]})
print(df.to_markdown())
