ANSWER

Answered 2022-Mar-28 at 21:21

You can't do it (not in the same code block).

You are thinking of the async/await pattern, but Cypress does not support it.

You can use a beforeEach() block to set a closure variable or an alias.

Here is a way using stack. First remove the _n from the columns names, then set_index the column id, mask the cell with empty string that would be remove when stacking the data. Then use reset_index and rename to fit the expected output.

QUESTION

Getting multiple variables in TensorFlow and other frameworks (overheads)

Asked 2021-Oct-06 at 08:10

If I have the following graph and want to get the values of tensors T1 and T2 in TF without eager execution, how would I do this? I only know of eval() or session.run() (running that twice could be an option) or tf.print(), but printing is not desired (for performance reasons).

Especially, how is this functionality implemented in TensorFlow? Does this impose a big overhead towards just getting T2? I would be happy to be pointed to relevant resources as well.

I'm generally looking for discussions on this -- if people want to add comparisons to how other frameworks do this (Caffe, Torch, CNTK, Theano, Chainer, DyNet, etc.), that's great! In the end, I am trying to understand how these frameworks could be expanded by operators that return operator-specfic metrics that a user can use to monitor training.

Thanks!

Answered 2021-Oct-06 at 08:10

you can pass multiple parameters to session.run, and it will run the network once and return each of those parameters.

Instead of adding the entire value of the style attribute, you can just add the value that you want to assert using include.

QUESTION

Cypress test if input field value has multiple lines

Asked 2021-Sep-06 at 08:38

I want to check with a cypress test if the value is correct in a single-line text fields and multi-line text area.

I here have a single line box where I use the code down below to add an input:

cy.followLabel("When did the incident happen?").type("single \nline");

Same thing for the multi line text area

cy.followLabel("Deenter code herescribe what happened").type("multiple \nlines");

I tried to validate it with .should() but haven't found any chainers that would suit my need.

Is there something like .contains("\n")?

I currently have a DeepPavlov bot running in a docker container and using the rise RESTAPI.

ANSWER

Answered 2021-Jul-08 at 16:15

No, there is no easy way to configure DeepPavlov to do this. You either should change DeepPavlov source code or write your own server with proper response format. In the second case, DeepPavlov model could be used with build_model method.
