Using the below pandas python dataframe. Show me how to create a new dataframe with each unique page and calculate the total_impressions_count for each unique page by date and include the top 5 query field values sorted by impressions for that given day.

EXAMPLE DATAFRAME DATA:
	id	date	query	page	country	device	clicks	impressions	ctr	avg_position	unique_hash
10988002	11409704	2022-10-21 pancakes	https://example.com/pancakes/	usa	DESKTOP	0	1	0.0	35.000000	d9e67cbc8afddd39a817fcbb9a8de3f8
Assuming your dataframe is named `df`, you can create a new dataframe with each unique page and calculate the total_impressions_count for each unique page by date and include the top 5 query field values sorted by impressions for that given day using the following code:

```
# Group by page and date, and sum the impressions
grouped = df.groupby(['page', 'date']).agg({'impressions': 'sum'})

# Get the top 5 queries by impressions for each page and date
top_queries = df.groupby(['page', 'date', 'query']).agg({'impressions': 'sum'}).reset_index()
top_queries = top_queries.sort_values(['page', 'date', 'impressions'], ascending=[True, True, False])
top_queries = top_queries.groupby(['page', 'date']).head(5)

# Merge the impressions and top queries dataframes
result = pd.merge(grouped, top_queries, on=['page', 'date'])

# Print the resulting dataframe
print(result)
```

This code first groups the dataframe by page and date, and sums the impressions column for each group to get the total impressions count. Then, it groups the dataframe by page, date, and query, and sums the impressions column again to get the impressions count for each query on each page and date. It then sorts the resulting dataframe by page, date, and impressions in descending order, and keeps only the top 5 queries for each page and date. Finally, it merges the two dataframes on page and date to get a dataframe that shows the total impressions count for each unique page by date, along with the top 5 query field values sorted by impressions for that given day.
Thank you. How can I create a simple regression model using Pytorch to predict impressions for a given date, using the dataframe and features provided? Include imports for all code.
To create a simple regression model using PyTorch to predict impressions for a given date, you can follow these steps:

1. Import the necessary libraries: PyTorch, NumPy, and Pandas:

```python
import torch
import numpy as np
import pandas as pd
```

2. Load the data from the CSV file into a Pandas DataFrame:

```python
data = pd.read_csv('data.csv')
```

3. Define the input and output variables:

```python
X = data.iloc[:, :-1].values
y = data.iloc[:, -1].values
```

4. Convert the data into PyTorch tensors:

```python
X = torch.FloatTensor(X)
y = torch.FloatTensor(y)
```

5. Define the model architecture:

```python
class LinearRegression(torch.nn.Module):
    def __init__(self, input_size, output_size):
        super(LinearRegression, self).__init__()
        self.linear = torch.nn.Linear(input_size, output_size)

    def forward(self, x):
        y_pred = self.linear(x)
        return y_pred

model = LinearRegression(input_size=X.shape[1], output_size=1)
```

6. Define the loss function and optimizer:

```python
criterion = torch.nn.MSELoss()
optimizer = torch.optim.SGD(model.parameters(), lr=0.01)
```

7. Train the model for a given number of epochs:

```python
num_epochs = 1000

for epoch in range(num_epochs):
    # Forward pass
    y_pred = model(X)

    # Compute loss
    loss = criterion(y_pred, y)

    # Backward pass and optimization
    optimizer.zero_grad()
    loss.backward()
    optimizer.step()

    # Print progress
    if (epoch+1) % 100 == 0:
        print(f'Epoch [{epoch+1}/{num_epochs}], Loss: {loss.item():.4f}')
```

8. Use the trained model to make predictions:

```python
# Predict impressions for a given date
date = np.array([[2022, 4, 10, 0, 0, 0]])  # features for the given date
date_tensor = torch.FloatTensor(date)
impressions_pred = model(date_tensor).item()

print(f'Predicted impressions for {date[0]}: {impressions_pred:.2f}')
```

Note that the above code assumes that the CSV file containing the data is named data.csv, and that the input data consists of the features for each date in the first columns of the CSV file, and the target (impressions) in the last column. You may need to modify the code to match the structure of your own data.

Also note that this is just a simple example of how to create a regression model using PyTorch. Depending on the complexity of your data and the problem you are trying to solve, you may need to use more advanced techniques and architectures.
