A tiny symbolic autodiff demo built on Sympy.
Project description
SymGrad4T
一个用 Sympy 做符号表达的极简自动求导/张量广播示例。支持基本张量算子（加减乘除、幂、求和、广播、LaTeX 输出等），附带示例脚本与测试。
运行测试
- 项目根目录执行：
pytest -q - 如需只跑库内测试：
cd SymGrad && pytest -q
运行示例
- 示例脚本：
SymGrad/run.py - 运行命令：
python SymGrad/run.py - 默认脚本构建一个简单的归一化与乘法组合，并打印
x、w的梯度（LaTeX 形式）。
已支持的 OP
- 加减乘除：
Add/Sub/Mul/Div（支持广播与标量/符号） - 幂：
Power（支持标量或张量指数，广播） - 平方根：
Sqrt - 维度求和：
Sum(dim, keepdim=False)（支持负索引与 keepdim） - 广播：
Broadcast/Tensor.broadcast_to - LaTeX 输出：
Tensor.latex_expr()/Tensor.latex_grad()
