A python script run well on jupyter notebook but not as py script

When working with Python, it is not uncommon to encounter situations where a script runs perfectly fine on Jupyter Notebook but fails to execute as a .py script. This can be frustrating, especially when you need to run the script outside of the Jupyter environment. However, there are several ways to solve this issue and ensure that your Python script runs smoothly as a .py file.

Option 1: Check for Dependencies

One possible reason for the script not running as a .py file is the absence of necessary dependencies. Jupyter Notebook often comes pre-installed with various libraries and packages, which might not be available in your Python environment. To resolve this, you need to identify the dependencies used in your script and ensure they are installed.

# Begin your Python code here
import pandas as pd
import numpy as np

# Rest of your code

In the above example, the script requires the pandas and numpy libraries. To install these dependencies, you can use pip, the Python package installer, by running the following commands in your terminal:

pip install pandas
pip install numpy

Once the dependencies are installed, you should be able to run the script as a .py file without any issues.

Option 2: Check File Paths

Another common reason for a script running on Jupyter Notebook but not as a .py file is incorrect file paths. Jupyter Notebook allows you to access files from any directory, but when running a .py file, the script’s location becomes the reference point for file paths. Therefore, you need to ensure that the file paths in your script are correct and accessible from the script’s location.

# Begin your Python code here
data = pd.read_csv('data.csv')

# Rest of your code

In the above example, the script reads a CSV file named ‘data.csv’. If the file is located in a different directory than the script, you need to provide the full file path or move the file to the same directory as the script.

Option 3: Check for Compatibility Issues

Lastly, compatibility issues between Jupyter Notebook and Python scripts can also cause discrepancies in execution. Jupyter Notebook allows you to execute code cells individually, which can lead to different variable states compared to running the entire script at once. To ensure compatibility, you can try the following:

# Begin your Python code here
# Add a cell at the beginning of the script to reset variables
%reset -f

# Rest of your code

The ‘%reset -f’ command resets all variables, ensuring a clean state before executing the script. This can help eliminate any discrepancies caused by running code cells individually in Jupyter Notebook.

After trying these different solutions, it is important to evaluate which option works best for your specific scenario. In most cases, checking for dependencies and file paths tend to be the most common culprits for scripts not running as .py files. However, compatibility issues can also arise, especially if your script heavily relies on code cell execution order. Therefore, it is recommended to thoroughly test your script after implementing each solution to ensure it runs smoothly as a .py file.

In conclusion, the best option to solve the issue of a Python script running well on Jupyter Notebook but not as a .py file depends on the specific problem at hand. However, checking for dependencies and file paths should be the first steps to take, followed by addressing any compatibility issues if necessary.

    Man, that Python script is playing a game of hide and seek! Maybe its secretly in love with Jupyter Notebook and wants to stay there forever. But seriously, its frustrating when things work in one place but not in another. Option 3 seems like the sneaky culprit here. Compatibility issues, you sly devil!
