从Seaborn导入鸢尾花数据集这个代码我运行不了 ![Uploading 微信图片_20240111122345.png…]()

Violetbit commented 8 months ago

iris_df = sns.load_dataset("iris")

使用seaborn.load_dataset函数加载Iris数据集

iris_df = sns.load_dataset("iris")

ValueError Traceback (most recent call last) Cell In[6], line 2 1 # 使用seaborn.load_dataset函数加载Iris数据集 ----> 2 iris_df = sns.load_dataset("iris")

File ~\anaconda3\Lib\site-packages\seaborn\utils.py:587, in load_dataset(name, cache, data_home, **kws) 585 if not os.path.exists(cache_path): 586 if name not in get_dataset_names(): --> 587 raise ValueError(f"'{name}' is not one of the example datasets.") 588 urlretrieve(url, cache_path) 589 full_path = cache_path

ValueError: 'iris' is not one of the example datasets.

重新装一下seaborn 或者，从scikit learn或plotly加载鸢尾花数据集

重装seaborn的方法失败，从scikit learn中导入成功但是iris.head()运行失败。从seaborn中导入的iris和scikit learn中导入的iris好像数据类型不一样

Visualize-ML commented 8 months ago

scikit learn特征数据是NumPy Array. 你再试试plotly导入

成功了，感谢

Book1_Ch07第7页isdigit()只对0和正整数有效，文章中表述“使用isdigit的方法检查输入是否是一个数值”存在问题

Visualize-ML commented 8 months ago

谢谢你，请继续批评指正。这个issue先开着，二月份修改。
