Not sure what pz is? about bap3 HOT 8 CLOSED

from bap3.

pz stands for preliz. Usually all imports are in the first cell of each notebook. You will see the line "import preliz as pz".

What error are you getting?

Thank you very much for your quick reply. I didn't see the import code in the book itself, but now that I go to the code in the github I can see it. That addresses my main error - now I just need to figure out how to use the bap3 environment in a Jupyter notebook but I can figure that out! Thanks again.

On Linux or Mac you run "conda activate bap3" from a terminal and then run "jupyter notebook". Not sure on Windows, but I think you can run the same commands if you first find and run the "Anaconda prompt" from the start menu.

Some IDES support notebooks. For instance VsCode supports notebooks (after installing a python plugin).

Thank you so much. That worked. I am self-taught and have previously only used terminal to run my python programs (not Jupyter) so just learning something new. Thanks for all your hard work on this.

Hi Osvaldo, sorry to bother you again. I am on Chapter 2 and tried to create my first model using the code:

with pm.Model() as our_first_model:
theta = pm.Beta('theta', alpha=1., beta=1.) # Specifies the prior
y = pm.Bernoulli('y', p=theta, observed=data) # Specifies the likelihood
idata = pm.sample(1000)

I have the right imports. I am getting a litany of errors (pages of messages) starting with this:

WARNING (pytensor.tensor.blas): Using NumPy C-API based implementation for BLAS functions.

You can find the C code in this temporary file: /var/folders/mf/bvt1s84s18b36l4wbn86s2lc0000gn/T/pytensor_compilation_error_fosqurhy

replacements = node_rewriter.transform(fgraph, node)

There are pages and pages of error notices with "7 errors generated" at the bottom. I'm really stuck after doing some more Googling and can't seem to figure out why I can't run the code. I have activated the bap3 environment in conda.

Is it possible I made errors while installing packages (using pip initially then moving to conda install)? And if so, how do I fix this?

Again, appreciate your time if you have a moment to help.

yeah, it seems you made a mistake while installing packages. You can try deleting the env and starting fresh. Or uninstalling pymc and pytensor, and installing them again. Just to be sure attempt to uninstall the packages using both pip and conda.
