Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
N2D2 is primarily developed in C++, which can be challenging for developers more familiar with higher-level languages like Python.
As a specialized tool, N2D2 has a smaller user base compared to more general-purpose frameworks such as TensorFlow or PyTorch, leading to fewer resources and slower issue resolution times.
Setting up the development environment for N2D2 can be cumbersome due to its dependencies on specific versions of libraries and tools, often requiring manual configuration.
While there is some Python integration, the primary development and usage are in C++, limiting flexibility for multi-language projects.
