EveryO is open source.

The repository includes implementations of tensors, autograd, neural layers, optimizers, and training utilities.

Explore the source

Q18. Does EveryO support type hints?

Yes.

The repository includes a py.typed package marker, and its contribution guidelines require type hints on public functions and methods.


4. Tensors and Numerical Computing

Q19. What is a Tensor in EveryO?

A Tensor is EveryO's primary numerical data structure.

It stores numerical values and supports mathematical operations, shape information, device information, and optional gradient tracking.

Q20. How do I create a tensor?
import everyo as eo

x = eo.tensor([1.0, 2.0, 3.0])

print(x)
Q21. Does EveryO support matrix multiplication?

Yes.

import everyo as eo

a = eo.tensor([[1.0, 2.0]])
b = eo.tensor([[3.0], [4.0]])

result = eo.matmul(a, b)

print(result)

The numerical result is 11.

Q22. Does EveryO support broadcasting?

Yes.

EveryO supports NumPy-style broadcasting for compatible tensor shapes.

Gradient propagation must correctly account for broadcast dimensions.

Q23. Can EveryO use float32 and float64?

Yes.

Tensor construction supports numerical dtype selection.

The appropriate dtype depends on accuracy, memory, and performance requirements.

Q24. How do I inspect tensor properties?
print(x.shape)
print(x.ndim)
print(x.dtype)
print(x.device)
print(x.size)

5. Automatic Differentiation

Q25. What is automatic differentiation?

Automatic differentiation computes derivatives by applying the chain rule through a graph of mathematical operations.

EveryO implements reverse-mode automatic differentiation, which is useful for neural network training.

Q26. How do I calculate a gradient?
import everyo as eo

x = eo.tensor(
    [2.0],
    requires_grad=True,
)

y = x * x

y.backward()

print(x.grad)

Expected gradient:

[4.]
Q27. What does requires_grad mean?

requires_grad=True tells EveryO to track operations involving the tensor so gradients can be computed during backpropagation.

Q28. Why is my gradient missing?

Possible causes:

  • Gradient tracking was disabled.
  • The tensor did not require gradients.
  • Backward was not called.
  • The computation occurred in a no_grad() context.

Review the graph construction and backward call.

Q29. What is no_grad used for?

no_grad() disables gradient graph construction for operations inside its context.

It is useful for inference.

with eo.no_grad():
    predictions = model(features)
Q30. How does EveryO verify gradient correctness?

The repository uses central finite-difference checks and comparisons with TensorFlow where applicable.

For a scalar function:

[ f'(x) \approx \frac{f(x+h)-f(x-h)}{2h} ]

Numerical tolerances are necessary because floating-point computations are not exact.


6. Neural Networks

Q31. Can I build a neural network?

Yes.

    eo.Linear(4, 16),
    eo.ReLU(),
    eo.Linear(16, 3),
)

trainer = eo.Trainer(
    model,
    eo.Adam(model.parameters(), lr=0.01),
    eo.CrossEntropyLoss(),
    metrics=["accuracy"],
)

history = trainer.fit(
    train_loader,
    epochs=20,
    validation_loader=validation_loader,
)

This example assumes train_loader and validation_loader have already been created.

Q40. Does EveryO support early stopping?

  • Missing driver.
  • Missing CUDA toolkit.
  • Native extension not built.
  • Incompatible environment.

Use everyo doctor for more information.

Q52. Are CUDA kernels fully hardware-validated?

The repository documents CUDA implementation and CPU-side tests, but its standard CI does not provide real GPU execution.

Hardware validation remains an important limitation.

Q53. Will CUDA always be faster?

No.

Performance depends on:

  • Tensor size.
  • Transfer overhead.
  • Kernel implementation.
  • Hardware.
  • Workload characteristics.

Small workloads may not benefit from GPU acceleration.


10. TensorFlow Integration

Q54. Does EveryO require TensorFlow?

No.

TensorFlow is optional.

Q55. Why does EveryO use TensorFlow comparisons?

TensorFlow provides an external reference for checking selected numerical and gradient results.

These comparisons help validate EveryO's own implementations.

Q56. How do I install TensorFlow support?
python -m pip install -e ".[tensorflow]"
Q57. Does installing TensorFlow automatically enable CUDA?

No.

TensorFlow GPU support and EveryO's native CUDA extension are separate capabilities with their own requirements.

Q58. Does EveryO support ONNX?

Yes.

EveryO includes optional ONNX export and ONNX Runtime integration.

Q59. How do I install ONNX support?
python -m pip install -e ".[onnx]"
Q60. Can I export a model to ONNX?

Yes, for supported architectures.

eo.export_onnx(
    model,
    "model.onnx",
    input_shape=(1, 4),
)
Q61. What is the tracing ONNX exporter?

The tracing exporter records primitive operations executed during a forward pass.

It supports architectures that may not be covered by the layer-based exporter.

Q62. Does ONNX tracing support every dynamic shape?

No.

Tracing can specialize to the example execution path and shapes.

Dynamic-batch support is conditional on validation.


12. Serialization and Model Files

Q63. Can EveryO save trained models?

Yes.

eo.save(model, "model.evo")
Q64. How do I load a saved model?
restored = eo.load("model.evo")
Q65. What is an .evo file?

An .evo file is EveryO's model archive format.

It contains structured model metadata and numerical parameters.

The archive is ZIP-based and uses JSON and NumPy parameter storage.

Q66. Does EveryO use pickle for model loading?

No.

EveryO's model serialization is designed to avoid pickle-based code execution.

The loader uses NumPy with allow_pickle=False and reconstructs models through registered module classes.

Q67. Can I load any external .evo file safely?

Treat downloaded model files as untrusted input.

The pickle-free design reduces a major code-execution risk but does not prove that every malformed or malicious archive is harmless.

Report any unexpected code execution privately.


13. Performance and Profiling

Q68. Is EveryO faster than PyTorch or TensorFlow?

EveryO does not claim to outperform optimized production frameworks.

Its primary goals are readability, experimentation, and numerical verification.

run.summary()
Q70. Can I export profiling traces?

Yes.

run.export_chrome_trace("trace.json")
Q71. Does EveryO support quantization?

Yes.

The repository documents dynamic int8 weight quantization.

compact = eo.quantize_dynamic(model)
Q72. Does quantization guarantee faster inference?

No.

The documented implementation focuses on compact weights and numerical fidelity.

It does not currently provide a dedicated optimized int8 inference kernel.


14. Distributed Training

Q73. Does EveryO support distributed training?

Yes.

The repository implements data-parallel training and TCP-based process-group functionality.

Q74. Has multi-machine training been fully validated?

Not in the documented CI environment.

The repository reports TCP communication testing across separate processes on one host, but not completed testing across two physical machines.

Q75. Is distributed communication encrypted?

The documented TCP process-group protocol assumes a trusted network and does not provide transport encryption.

It should not be exposed to untrusted networks.

Q76. Does using multiple workers always improve performance?

No.

Distributed execution introduces synchronization, communication, and process-management overhead.

Benefits depend on workload and environment.
