Mar 13Using Python with C++. Part4.Using Python and C++ together using Pybind library. Summary In this story we will talk about Opaque Types and managing std::vector inside python. A brief introduction Let’s recap what we found in the previous part. We saw that passing std::vector by reference to functions did not work. We used some workarounds to avoid these…Python Programming3 min readPython Programming3 min read
Mar 10Using Python with C++. Part3.Using Python and C++ together using Pybind library. Summary In this episode we are going to use numpy arrays and python lists to handle data that will passed to some c++ functions to do some additional calculations. Process some data Let’s take as example a function ProcessSomeData that calculates the square of an input…Python Programming4 min readPython Programming4 min read
Mar 6Using Python with C++. Part2.Using Python and C++ together using Pybind library. In the previous episode… In the first part i made an example on how to call from a python script a C++ function, this time let’s go further and explore more advanced use cases.

Feb 26A quick journey through Conv1D functions from TensorFlow to PyTorch, passing via SciPy. Part 3Causal Convolution In this story we will talk about other two types of convolution: Causal convolution Full convolution First of all let’s recall the definition of a causal system: A system is called causal if : y(t0) = f(x(t)) with t ≤ t0, in words: the output y of a system S…Pytorch4 min readPytorch4 min read
Feb 25A quick journey through Conv1D functions from TensorFlow to PyTorch, passing via SciPy. Part 2Convolution, Same Mode We continue the journey from the first part, talking about the same modality in convolution operations. From the TensorFlow library documentation we read that the same modality results in padding evenly to the left/right of the input such that output has the same size dimension as the input. Remembering what…Pytorch4 min readPytorch4 min read
Feb 15A quick journey through Conv1D functions from TensorFlow to PyTorch, passing via SciPy.So, what about this article? When i started using TensorFlow i was relatively new to ML libraries and ML concepts. First times were hard because i did not know how to properly manage tensors, dimensions, shapes, reshapes, how layers expected to have input tensors and produce output tensors, etc. …Conv1d4 min readConv1d4 min read
Sep 28, 2022Managing python environments with conda made simple.Before we start.. Ok, what is Conda ? Reading the website https://docs.conda.io/en/latest/, we find that Conda is an open source package management system and environment management system that runs on Windows, macOS, Linux and z/OS. What is an environment and why do i need one ? An environment is basically a folder where…Python2 min readPython2 min read
