Seaborn ValueError : ID가없는 축소 작업 최소값에 대한 크기가 0 인 배열

Aug 16 2020

나는 자신의 웹 사이트 에서이 산점도 seaborn 예제를 실행했습니다 .

import seaborn as sns; sns.set()
import matplotlib.pyplot as plt
tips = sns.load_dataset("tips")

# this works:
ax = sns.scatterplot(x="total_bill", y="tip", data=tips)

# But adding 'hue' gives the error below:
ax = sns.scatterplot(x="total_bill", y="tip", hue="time", data=tips)

이 오류 :

어제는 작동했습니다. 그러나 conda update --all. 변경된 사항이 있습니까?

무슨 일이야?

Linux 컴퓨터에서 파이썬을 실행합니다.

Pandas:  1.1.0.
Numpy:   1.19.1.
Seaborn api:  0.10.1.

  • 이 문제는 다음에 대해 해결 된 것 같습니다. matplotlib==3.3.2
  • seaborn : 산점도는 matplotlib == 3.3.1 # 2194로 실패합니다.
  • matplotlib버전3.3.1
  • 해결 방법은 보낼 수 있습니다 list에를 hue사용하여,.tolist()
    • 사용 hue=tips.time.tolist().
  • 정상적인 동작은 추가 title전설에 있지만 전송 list하려면 hue범례 제목을 추가하지 않습니다.
    • 범례 제목은 수동으로 추가 할 수 있습니다.
import seaborn as sns

# load data
tips = sns.load_dataset("tips")

# But adding 'hue' gives the error below:
ax = sns.scatterplot(x="total_bill", y="tip", hue=tips.time.tolist(), data=tips)
ax.legend(title='time')  # add a title to the legend

conda install -c conda-forge matplotlib==3.3.03.3.1에서 알려진 오류 가 주어졌습니다.

정답이지만 훌륭한 솔루션은 아닙니다.
