pandas_profiling main method not working correctly... Constructor works but not method

Question

df.profile_report() fails immediately after installation using import pandas_profiling

The package is installed properly, because I can generate a report in Jupyter by importing and using just the constructor ProfileReport(df). However, the syntax df.profile_report() does not work.

When I run df.profile_report() I get an error message below:

```AttributeError Traceback (most recent call last)
in 
----> 1 df.profile_report()

C:\Anaconda3\envs\quantecon\lib\site-packages\pandas\core\generic.py in getattr(self, name)
5065 if self._info_axis._can_hold_identifiers_and_holds_name(name):
5066 return self[name]
-> 5067 return object.getattribute(self, name)
5068
5069 def setattr(self, name, value):

AttributeError: 'DataFrame' object has no attribute 'profile_report'
```

Version information: Python 3.7.1 pandas==0.24.2

```import numpy as np
import pandas as pd
from pandas_profiling import ProfileReport

# The dataframe is the same as the tutorial example given by the author.  

df = pd.DataFrame(np.random.rand(100, 5), columns=['a', 'b', 'c', 'd', 'e'])    

df.profile_report() # this fails.```

What else I've tried that does work is as follows: from pandas_profiling import ProfileReport ...steps to create dataframe df ProfileReport(df)

Using the constructor ProfileReport(df) by itself at least gets me a report in my Jupyter Notebook. Because of this I know the package is installed and working. However, the object.method() route to get the report doesn't work. But many other methods rely on the object.method() syntax.

I cannot get any dataframes work with the df.profile_report() method.

```import numpy as np
import pandas as pd
from pandas_profiling import ProfileReport

# The dataframe is the same as the tutorial example given by the author.  

df = pd.DataFrame(
    np.random.rand(100, 5),
    columns=['a', 'b', 'c', 'd', 'e']
)    

df.profile_report() # this fails.
ProfileReport(df)  # this works, but `df.profile_report()` does not work.
```

My guess as to what's wrong...?

Since the pandas error is referring to "generic.py" for Pandas Core DataFrame, and the error is "no attribute 'profile_report', perhaps it is the decorator that wraps the dataframe object and modifies it to give it the extra attribute method of .profile_report() ?? That is my guess. I don't know what's causing the error, since it works when I "peek under the covers" and use the report constructor directly. I just cannot use the other methods that rely on the object.method() syntax.

The .profile_report() syntax was introduced in pandas_profiling version 2.

You can install this version via pip: pip install pandas-profiling.

EDIT

The way to import the package is:

import pandas_profiling

in contrast to your current approach

from pandas_profiling import ProfileReport

Try this:

import pandas_profiling

pandas_profiling.describe_df(data_df)
html_str_output = pandas_profiling.ProfileReport(data_df)
