BUG: When compute.use_numba is enabled, pandas.DataFrame.info() will raise an error due to a data type issue with pandas.core.frame.DataFrameInfo.dtype_counts.

Pandas version checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pandas.

• I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

import pandas as pd
pd.set_option('compute.use_numba', True)

df = pd.DataFrame([[1, 2], [3, 4]])
df.info()

"""
...
ValueError: Unknown format code 'd' for object of type 'float'
"""

Issue Description

I'm sorry to inform you that my current pandas environment can only be updated to version 1.5.2, and this bug exists in this version. If the bug has been fixed in version 1.5.3, I will wait for the maintainers to update it.

When compute.use_numba is disabled,

pd.set_option('compute.use_numba', False)

info = pd.core.frame.DataFrameInfo(df)
print(info.dtype_counts)
"""
int64    2
dtype: int64
"""

When compute.use_numba is enabled,

pd.set_option('compute.use_numba', True)

info = pd.core.frame.DataFrameInfo(df)
print(info.dtype_counts)
"""
int64    2.0
dtype: float64
"""

The count of data types in the dtype Series has changed from int to float. This causes an error in the code called by the DataFrame.info() function.

    779 def add_dtypes_line(self) -> None:
    780     """Add summary line with dtypes present in dataframe."""
    781     collected_dtypes = [
--> 782         f"{key}({val:d})" for key, val in sorted(self.dtype_counts.items())
    783     ]
    784     self._lines.append(f"dtypes: {', '.join(collected_dtypes)}")

ValueError: Unknown format code 'd' for object of type 'float'

Expected Behavior

import pandas as pd
pd.set_option('compute.use_numba', True)

df = pd.DataFrame([[1, 2], [3, 4]])
df.info()

<class 'pandas.core.frame.DataFrame'>
RangeIndex: 2 entries, 0 to 1
Data columns (total 2 columns):
 #   Column  Non-Null Count  Dtype
---  ------  --------------  -----
 0   0       2 non-null      int64
 1   1       2 non-null      int64
dtypes: int64(2)
