problems with tfp.sts.fit_with_hmc

11

I'm having a few issues with `tfp.sts.fit_with_hmc` so thought I would reach out, I am using a very recent tfp-nightly and tensorflow 2 alpha. Firstly, the function signature has `num_variational_steps=150`...

Hi, As far as I can see, `MySQL.load` does not use any information about column names and I think this can lead to bad behaviour, see for example: ``` julia...

numpyro and pymc have a zero sum normal distribution based on a zero sum bijector, (see e.g. [numpyro zero sum normal](https://num.pyro.ai/en/stable/distributions.html#zerosumnormal) and [numpyro zero sum transform](https://num.pyro.ai/en/stable/distributions.html#numpyro.distributions.transforms.ZeroSumTransform))). I was wondering if...

Hi, I found that `sample_distributions` can error when using the jax substrate. `sample` seems to be ok, using tf appears to be ok, and using the non auto batched joint...

[WIP] experimental Laplace approximation

Hello, as per the discussion in #1178 I've started to code up how a Laplace approximation over a joint distribution could look. It's still very much WIP as these things...

Copulas and discrete random variables

I've been following [Copulas Primer](https://www.tensorflow.org/probability/examples/Gaussian_Copula) which constructs a bivariate distribution using Kumaraswamy and Gumbel marginals, with the copula inducing correlation between the two. This seems possible since there is `tfb.KumaraswamyCDF`...

I am trying to run many time series models with different initial states via batching, it seems to be supported in some parts of the code although not explicit in...

Hi, I have the following minimal code example: ``` c++ #include #include #include // 3.4.0 #include struct Objective { double operator()(const double x) const { Eigen::VectorXd y = Eigen::VectorXd::Zero(2); y[0]...

Hi, if I try the following code: [Enzyme Explorer link](https://fwd.gymni.ch/g8plpr) ``` c++ #include #include struct objective { double operator()(double x) { return x * 10; } }; int main() {...

Hi, I am trying to create some simple autodiff examples using [Eigen](https://eigen.tuxfamily.org/index.php?title=Main_Page). I am using Enzyme v0.0.195 and clang 18. ``` c++ #include #include template void __enzyme_autodiff(void*, T...); int enzyme_dup;...
