Spago

Spago, being a relatively new library in the Go ecosystem for ML/NLP, has a smaller user base and fewer contributors compared to more established Python libraries like TensorFlow or PyTorch.

While Spago offers a wide range of algorithms, it may not cover all the advanced models found in more mature ML frameworks such as TensorFlow and PyTorch, which could limit its applicability for cutting-edge research.

Go's garbage collector can introduce pauses that may affect the real-time performance of ML models, especially in high-throughput scenarios where low latency is critical.

Spago does not natively support GPU acceleration, which can be a significant limitation when dealing with large datasets or complex models that require substantial computational power.
