I am having the same error as above on line 34 of ```mean_squared_error_impl.hpp```, ```C2228left of '.n_cols' must have class/struct/union```. As above, attempting to use ```mlpack::ann::FFN < mlpack::ann::MeanSquaredError<>> policyNetwork(mlpack::ann::MeanSquaredError<>{});
<genisispig[m]>
``` as a network in the SAC implementation causes this error. However, with other error functions, such as ```mean_squared_logarithmic_error```, I am experiencing different, but still build halting, errors
<turska79turska79>
If i use mlpack::ann::EmptyLoss<> then it works as its Forward() method simply returns 0;

The SAC implementation I believe is also missing the ```EnviromentType& Enviroment();``` and ```const EnvironmentType& Environment() const``` functions

<turska79turska79>
FFN has Forward/Backward as template methods, but SAC calls to them are without template parameters as: learningQ1Network.Forward(learningQInput, Q1);
<turska79turska79>
Shouldnt this be something like learningQ1Network.template Forward<>()?
