'DataFrame' object has no attribute 'reshape'

This error occurs when you try to use the `reshape()` method on a pandas DataFrame object. The `reshape()` method is not available for DataFrames, but only for numpy arrays.
To reshape a DataFrame, you can use the `pivot()` or `melt()` methods depending on your requirement.
For example, if you want to reshape the DataFrame by pivoting the values of a column, you can use the `pivot()` method as follows:
```
df = df.pivot(index='column1', columns='column2', values='column3')
```
Here, `column1` and `column2` are the columns that will form the new index and columns of the DataFrame, and `column3` is the column whose values will be used to fill the new DataFrame.
If you want to reshape the DataFrame by melting it, you can use the `melt()` method as follows:
```
df = df.melt(id_vars=['column1', 'column2'], value_vars=['column3', 'column4'])
```
Here, `column1` and `column2` are the columns that will remain as is, and `column3` and `column4` are the columns that will be melted into a single column.
