Word cloud resolution error

[gonzalezhomar]

Current Behaviour

The ProfileReport fails to generate, and i dont find if the issue is already solved or a way to bypass it.

I think because of the size of my data, it fails to generate the wordcloud.

The full error output is:

Expected Behaviour

I'm expecting the ProfileReport to generate, but skipping the wordclouds.

Maybe an option to turn the wordclouds off, so the profile generates but skips that.

Data Description

My data is private, about 2 million rows and +200 columns. Can't identify the column (s ???) that is causing the error.

Code that reproduces the bug

import pandas as pd
from ydata_profiling import ProfileReport
profile=ProfileReport(df, title="my_data_report", minimal=True)
profile

pandas-profiling version

v4.6.1

Dependencies

pandas==2.0.3

OS

Windows 11

Hello there. I'm experiencing the same issue here. So far, I´ve tried to removepart of the string coming from the categorical column to try to make an smaller string, using this function . Unfortunaltely , I am not able to make it work yet.

def remove_substring_from_column(df, column_name, substring, inplace=True):
    """
    Removes a specified substring from a particular column in a DataFrame.

    Parameters:
    - df (pandas.DataFrame): The input DataFrame.
    - column_name (str): The name of the column from which the substring should be removed.
    - substring (str): The substring to remove.
    - inplace (bool, optional): If True, modifies the input DataFrame directly. If False, returns a modified copy. 
                                Defaults to True.

    Returns:
    - pandas.DataFrame or None: If inplace is False, returns a modified copy of the DataFrame. 
                                If inplace is True, returns None and the input DataFrame is modified in place.
    """
    if inplace:
        target_df = df
    else:
        target_df = df.copy()

    if column_name in target_df.columns:
        print(f"Before removal: {target_df[column_name].head()}")
        target_df[column_name] = target_df[column_name].str.replace(substring, '', regex=False)
        print(f"After removal: {target_df[column_name].head()}")
    if not inplace:
        return target_df
    print('# ----data removed----#' + str(substring) + ' ' + str(column_name))
    return target_df`

Maybe decreasing the font size or increasing the Canvas Size might work. Anyone has any idea of how to tackle this , beyond trying changing the string length or doing a label encoding step ?
🙏🙏 Thanks for the time dedicated to tackle this issue ! 🙏🙏

Hi @SoyGema and @gonzalezhomar ,

can you please share what is the python version that you are using? And how are you installing ydata-profiling in your env (pip, conda, etc.)

[SoyGema]

Hi there. we are using . ydata-profiling is installed via pip

Python 3.10.12
ydata-profiling 4.5.0

[jonathanyulan99]

Following...I am running into the same problem, utilizing both 4.5 and 4.6 ydata-profiling with the above error message and the output being: <Figure size 600x400 with 0 Axes>

[sdbeuf]

Same issue here

Python 3.11.5
pandas 2.0.3
ydata_profiling v4.6.2

[fabclmnt]

Thank you for the information provided!

This issue is related with the wordcloud plot. We will analyze the issue in more detail, and considered it for the next release expected for mid January.

[BoPeng]

Just to get around of this error, I change generate_from_frequencies(word_dict) to generate_from_frequencies(word_dict, max_font_size=10) in

https://github.com/ydataai/ydata-profiling/blob/b0c422b2e06de5eb3ae41af68ac565ffc5aef9af/src/ydata_profiling/visualisation/plot.py#L38-L40

to avoid automatic determination of max_font_size. This is of course not ideal so I will be waiting for a proper solution.

[somnambWl]

For me, the cause of the problem was that I included in the dataframe also very long ID strings. When removed, the profiling started to work again :)

I'm having a similar issue - @fabclmnt was that issue resolved in the Jan (01/2024 i guess) version? @gonzalezhomar , did you manage to turn off word cloud?
