In this example, we use the data.frame() function to create an empty data frame named delftstack.We initialize vectors of different types (double, integer, factor, logical, and character) within the function call, defining the structure of the data frame explicitly. The stringsAsFactors = ...
The evaluation code for the generator looks largely similar to what we had in Step 6 except it has additional steps to initialize the RAG chain and invoke it for each question in our evaluation dataset in order to generate answers: 1 from ragas.metrics import faithfulness, answer_relevancy 2 ...
The only difference here is that we have to initialize each cell in addition to a sheet with thecell(row,col)method in theopenpyxllibrary. Theopenpyxlis also an external library. We need to install this library for this method to work properly. The command to install theopenpyxllibrary on ...
The problem is that we can’t simply try to call the API function on an htmlwidget before it’s created, because the function would simply not return anything since the widget takes time to initialize. We need to somehow delay the API functions to only run after the widget initializes. ...
In all cases, the basic approach for data transforms is the same. The heart of the RevoScaleR data step is a list oftransforms, each of which specifies an R expression to be evaluated. The data step typically is an assignment that either creates a new variable or modifies an existing varia...

To check if a column exists in a Pandas DataFrame, we can take the following Steps − Steps Create a two-dimensional, size-mutable, potentially heterogeneous tabular data,df. Print the input DataFrame,df. Initialize acolvariable with column name. ...
Also, if you have not created a MongoDB Atlas instance for yourself, you can follow the tutorial to create one. This will provide you with your MONGODB_CONNECTION_STR. Run the following lines of code in Jupyter Notebook to initialize the Cohere secret or API key and MongoDB Atlas c...
You can also save data in CSV format for analysis: class SaveToCSV: def open_spider(self, spider): self.data = [] def process_item(self, item, spider): self.data.append(item) return item def close_spider(self, spider): df = pd.DataFrame(self.data) ...
