UnboundLocalError: local variable 'hv_all' referenced before assignment

[priamai]

Hi there, I am doing the simple test:

import pandas as pd
from autoviz import AutoViz_Class

AV = AutoViz_Class()
custom_plot_dir = "marketing"
data = {'col1': [1, 2, 3, 4, 5], 'col2': [5, 4, 3, 2, 1]}
df = pd.DataFrame(data)

dft = AV.AutoViz(
    "",
    sep=",",
    depVar="",
    dfte=df,
    header=0,
    verbose=1,
    lowess=False,
    chart_format="html",
    max_rows_analyzed=150000,
    max_cols_analyzed=30,
    save_plot_dir=custom_plot_dir
)

Seems like hv_all was not declared?

This happens when the hv_all object is not created at all. If you have a snippet of data set (100 rows) and if you can post it here as a zip file attachment, I can find out what the problem is.  Can you also post what the code snippet is when you call AutoViz?Thanks for trying out AutoViz,Auto Vimal On Sunday, September 3, 2023 at 06:52:45 PM EDT, priamai @.***> wrote:

Hello you don't need my dataset, as I have shown in the previous post, this fails in the standard example that you provided. Just to highlight the data line is below:

data = {'col1': [1, 2, 3, 4, 5], 'col2': [5, 4, 3, 2, 1]}
df = pd.DataFrame(data)

Hey I might need to close this issue since you have not responded to my question with a real world example dataset. Let me know if you have one.Auto Vimal On Tuesday, September 5, 2023 at 09:12:59 AM EDT, priamai @.***> wrote:

Hello I see now what you meant, because that is small but this worked

import pandas as pd
from autoviz import AutoViz_Class

AV = AutoViz_Class()
custom_plot_dir = "autocar"
df = pd.read_csv("https://raw.githubusercontent.com/plotly/datasets/master/auto-mpg.csv")

dft = AV.AutoViz(
    "",
    depVar="",
    dfte=df,
    header=0,
    verbose=1,
    lowess=False,
    chart_format="html",
    max_rows_analyzed=150000,
    max_cols_analyzed=30,
    save_plot_dir=custom_plot_dir
)

Closing now!

Same problem solved, I think it's better to set this as the sample, or mark out that the standard DataFrame is not meant to be run, just a format. :D
