I was working on a deep learning project where I needed to build a neural network model in Python using TensorFlow Keras. But when I tried to import the library, I ran into the dreaded error, “ModuleNotFoundError: No module named ‘tensorflow.keras’.” If you’ve ever faced this issue, don’t worry. I’ve been developing in Python for … Read more >>
When I first started working with deep learning in Python, one of the biggest challenges I faced was figuring out how to properly save and reload my Keras models. After spending hours training a neural network, the last thing you want is to lose your progress or have to retrain your model from scratch. Over … Read more >>
Recently, while working on a deep learning project in Python, I faced a challenge saving my Keras model that used a custom layer. Everything worked fine during training, but when I tried to reload the model, I got an error saying the custom layer wasn’t recognized. If you’ve ever built custom layers in Keras and … Read more >>
While working on a deep learning project for a U.S.-based retail analytics company, I needed to quickly build and test a neural network model using Keras in Python. Even though I’ve been using Keras for over four years, I realized that many beginners still struggle with one basic step: how to import Keras from TensorFlow … Read more >>
When I first started working with Keras in Python, one of the biggest challenges I faced was figuring out how to properly save my trained models. After spending hours training a neural network, I wanted to make sure I could reuse it later without retraining from scratch. Saving a Keras model is one of those … Read more >>
In a Python data visualization project for a U.S. retail analytics dashboard, I had to invert the Y-axis in a 3D Matplotlib chart. The challenge was simple but tricky. I wanted the Y-axis to start from the maximum value and go down to the minimum, just like how some geographic or financial models are visualized. … Read more >>
Working on a data visualization project for a U.S.-based retail company, I needed to compare two different metrics, monthly sales revenue and customer satisfaction scores, on the same chart. The challenge was that both datasets had completely different scales. The sales numbers were in thousands, while the satisfaction scores were on a scale of 1 … Read more >>
I was working on a Python data visualization project where I had to display an image using Matplotlib’s imshow() function, but the image appeared upside down. It took me a moment to realize that the y-axis was inverted by default in imshow(). Since I’ve spent over a decade working with Python and Matplotlib, I’ve faced … Read more >>
When I first started using Matplotlib in Python over a decade ago, I often found myself struggling with simple but frustrating formatting issues. One of those was flipping or rotating the Y-axis label. If you’ve ever plotted data and realized that your Y-axis label is upside down, misaligned, or just not visually appealing, you’re not … Read more >>
Recently, while working on a Python data visualization project for a US-based retail analytics company, I needed to export a summary table created with Matplotlib into a clean, printable PDF format. At first, I assumed there would be a direct function in Matplotlib to save tables as PDFs, but I quickly realized that the process … Read more >>
