Unable to plot histograms in jupyter notebook

Question

I'm unable to plot the histogram in Jupyter notebook. Here's the code below and the error message in response to it.

import pandas as pd import numpy as np from sklearn.datasets import load_boston import matplotlib.pyplot as plt housing_data = load_boston() %matplotlib inline housing_data.hist(bins = 50, figsize = (20, 15)) plt.show() KeyError Traceback (most recent call last) /anaconda3/lib/python3.6/site-packages/sklearn/utils/__init__.py in __getattr__(self, key) 60 try: ---> 61 return self[key] 62 except KeyError: KeyError: 'hist' During handling of the above exception, another exception occurred: AttributeError Traceback (most recent call last) <ipython-input-17-570a88b85d5d> in <module>() ----> 1 housing_data.hist(bins = 50, figsize = (20, 15)) 2 plt.show(); /anaconda3/lib/python3.6/site-packages/sklearn/utils/__init__.py in __getattr__(self, key) 61 return self[key] 62 except KeyError:

---> 63 raise AttributeError(key) 64 65 def setstate(self, state):

AttributeError: hist

I'm new to this and please help me with this.

You're missing plot in your call: housing_data.plot.hist(...) should do it — busybear

@busybear, I tried using housing_data.plot.hist() and I get AttributeError: plot — vivek

Ah my bad. I just assumed housing_data was a pandas dataframe. The plot.hist method is specific for pandas dataframes. housing_data is a dictionary, more or less; you need to figure out how you want to deal with that or what data from there you want to plot. — busybear

import pandas as pd import numpy as np from sklearn.datasets import load_boston import matplotlib.pyplot as plt housing_data = load_boston() %matplotlib inline pd.DataFrame(housing_data['data']).hist(bins = 50, figsize = (20, 15))

you have to access dictionary of numpy array that contains data and than convert it to pandas dataframe in order to use .hist

great! Glad that I helped! If you have question feel free to ask. If the question is answered please check the tick under the answer =)

You didn't specify so I assumed you wanted to plot 'target'?

import pandas as pd import numpy as np import matplotlib.pyplot as plt from sklearn.datasets import load_boston housing_data = load_boston() housing_data_2 = ({'target' : list(housing_data['target'])}) df = pd.DataFrame(data=housing_data_2) df.plot.hist(bins = 50)
