Data Analysis with Python Projects - Medical Data Visualizer - Figure Settings

allanrovieira · September 27, 2023, 5:46pm

Tell us what’s happening:
Describe your issue in detail here.

I believe my problem is that figure settings are matching with the correct answer.
But I can’t see it.
Oh, and use the command in shell
pip install seaborn
But, in my code sns.catplot is in red, saying that :“catplot” is not a known member of module “seaborn” (function) catplot: Unknown

Your code so far

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
import numpy as np

# Import data
df = pd.read_csv("medical_examination.csv")

# Add 'overweight' column
df_over = df['weight']/((df['height']/100)**2)
bynario = df_over > 25
df['overweight'] = bynario.astype(int)

# Normalize data by making 0 always good and 1 always bad. If the value of 'cholesterol' or 'gluc' is 1, make the value 0. If the value is more than 1, make the value 1.
df.loc[df['cholesterol'] == 1 , 'cholesterol'] = 0 ## troca 1 ------> 0
df.loc[df['cholesterol'] >= 2 , 'cholesterol'] = 1 ## troca 1 ------> 0
df.loc[df['gluc'] == 1 , 'gluc'] = 0 ## troca 1 ------> 0
df.loc[df['gluc'] >= 2 , 'gluc'] = 1 ## troca 1 ------> 0


# Draw Categorical Plot
def draw_cat_plot():
  # Create DataFrame for cat plot using `pd.melt` using just the values from 'cholesterol', 'gluc', 'smoke', 'alco', 'active', and 'overweight'.
  teste_sea = df[['cardio','cholesterol','gluc','smoke','alco','active','overweight']]
  df_cat = pd.melt(teste_sea,id_vars=['cardio'], value_vars=['cholesterol','gluc',                                                    'smoke','alco','active','overweight'])


  # Group and reformat the data to split it by 'cardio'. Show the counts of each feature. You will have to rename one of the columns for the catplot to work correctly.
  count = df_cat.groupby(['cardio', 'variable', 'value']).size().reset_index()
  df_cat = count.rename(columns={0 : 'total'}) 
    

  # Draw the catplot with 'sns.catplot()'
  graph = sns.catplot(data=df_cat, kind="bar", x="variable", y="total", hue="value", col="cardio")



    # Get the figure for the output
  fig = graph.fig


    # Do not modify the next two lines
  fig.savefig('catplot.png')
  return fig


# Draw Heat Map
def draw_heat_map():
    # Clean the data
  df_heat = df[(df['ap_lo'] <= df['ap_hi']) & 
  (df['height'] >= df['height'].quantile(0.025)) & 
  (df['height'] <= df['height'].quantile(0.975)) & 
  (df['weight'] >= df['weight'].quantile(0.025)) & 
  (df['weight'] <= df['weight'].quantile(0.975))]

    # Calculate the correlation matrix
  corr = df_heat.corr()

    # Generate a mask for the upper triangle
  mask = np.triu(np.ones_like(corr)) 



    # Set up the matplotlib figure
  fig, ax = plt.subplots()

    # Draw the heatmap with 'sns.heatmap()'
  sns.heatmap(corr, center = 0.0 ,vmax = 0.319, vmin = -0.159 ,annot=True, mask = mask, fmt='.1f')



    # Do not modify the next two lines
  fig.savefig('heatmap.png')
  return fig

For future reference, if you’re looking for help dealing with an error, it can be helpful to include the entire stack trace in your post.
Based on your statement
“But, in my code sns.catplot is in red, saying that :“catplot” is not a known member of module “seaborn” (function) catplot: Unknown”
Here are some first steps:

catplot was introduced in version 0.9.0. If you have an older version of Seaborn installed, you won’t have access to it. You can either run 'pip install seaborn --upgrade
’ in your command line, or if you’re trying to run this code in an IDE, your IDE might require you to use their built-in package management system to install and upgrade packages.
Some IDEs or editors cache libraries and sometimes this cache might be outdated or corrupted. Restarting your editor or clearing its cache (depending on the editor) might resolve the problem.
Worst case scenario, if you need to just get this running fast and can’t track down the issue, , you can always use the older functions that catplot is built upon, like sns.factorplot.

pkdvalis · September 27, 2023, 7:27pm

But I can’t see it.

What do you mean here, you can’t see the chart or figures? It’s not generating an image? There’s an image but it’s blank?

Do you get any errors when you run the pytest?

Can you link to your replit?

Hi! Thank you very much for the answer.

I tried [3]…but I got this: AttributeError: module ‘seaborn’ has no attribute ‘factorplot’

I tried [1] , but I still got the erro message (below)

Oh…I’m really sorry… I meant that I couldn’t see my mistake.

Could you respond with your seaborn version so we can rule that out?

allanrovieira · September 27, 2023, 9:17pm

pip show seaborn

j.tranquilli · September 28, 2023, 2:44am

Have you run ‘pip install seaborn’ in your command line? Does your IDE have its own package manager? If so does it say that it is installed when you check there?

pkdvalis · September 28, 2023, 2:48am

Same error many people have had lately: https://forum.freecodecamp.org/t/data-analysis-with-python-projects-medical-data-visualizer-heatmap-values/639407/1

Fork this new boilerplate template, and copy your code back in: https://replit.com/@pkdvalis/fcc-2023-Boilerplate-medical-data-visualizer

I haven’t found a root cause but this seems to get around the problem.

allanrovieira · September 29, 2023, 8:09pm

Thank you, @j.tranquilli and @pkdvalis .

I followed the instructions … now ‘test_module.py’ and ‘main.py’ worked perfectly!
