import numpy as np

# 2. Configure NumPy Display Options
np.set_printoptions(precision=3)           # Set decimal precision
np.set_printoptions(suppress=True)         # Suppress scientific notation
np.set_printoptions(threshold=1000)        # Limit array display size
np.set_printoptions(edgeitems=3)          # Number of edge items to show

# 3. Configure Array Data Types
# Specify data types when creating arrays
arr_int = np.array([1, 2, 3], dtype='int64')
arr_float = np.array([1.0, 2.0, 3.0], dtype='float64')
arr_complex = np.array([1+2j, 3+4j], dtype='complex128')

# 4. Configure Array Shape and Dimensions
# Create arrays with specific shapes
arr_2d = np.array([[1, 2, 3], [4, 5, 6]], dtype='float64')

Array Preparation and Customization

Prepare and customize arrays for NumPy numerical computing:

# Array Preparation Examples:

import numpy as np

# 1. Create Arrays:
arr = np.array([1, 2, 3, 4, 5])
arr2d = np.array([[1, 2, 3], [4, 5, 6]])
arr_range = np.arange(0, 10, 2)

# 2. Explore Arrays:
print(arr)
print(arr.shape)
print(arr.dtype)
print(arr.size)
print(arr.ndim)

# 3. Handle Missing Data:
# Using masked arrays for missing values
import numpy.ma as ma
arr_with_missing = np.array([1, 2, -999, 4, 5])
masked = ma.masked_where(arr_with_missing == -999, arr_with_missing)
cleaned_mean = ma.mean(masked)

# Using NaN for missing values
arr_nan = np.array([1.0, 2.0, np.nan, 4.0, 5.0])
cleaned = arr_nan[~np.isnan(arr_nan)]

# 4. Transform Arrays:
# Convert data types
arr_int = arr.astype('int64')
arr_float = arr.astype('float64')

# Create new arrays from existing
arr_doubled = arr * 2
arr_squared = arr ** 2
arr_normalized = (arr - np.mean(arr)) / np.std(arr)

# 5. Filter Arrays:
filtered = arr[arr > 3]
filtered = arr[(arr > 2) & (arr < 5)]

# 6. Aggregate Operations:
summary = {
    'sum': np.sum(arr),
    'mean': np.mean(arr),
    'std': np.std(arr),
    'min': np.min(arr),
    'max': np.max(arr)
}

# 7. Save Prepared Arrays:
np.save('output/prepared_array.npy', arr)
np.savetxt('output/prepared_array.csv', arr, delimiter=',')

# Continue with notebooks for more operations

Saving and Loading Arrays

Save and load NumPy arrays in different formats:

# Save and Load NumPy Array Examples:

# 1. Save to .npy format (NumPy native):
import numpy as np
arr = np.array([1, 2, 3, 4, 5])

# Basic .npy save
np.save('output.npy', arr)

# Load from .npy
loaded = np.load('output.npy')

# 2. Save to .npz format (compressed archive):
# Save multiple arrays
arr1 = np.array([1, 2, 3])
arr2 = np.array([4, 5, 6])
np.savez('arrays.npz', arr1=arr1, arr2=arr2)

# Load from .npz
data = np.load('arrays.npz')
loaded_arr1 = data['arr1']
loaded_arr2 = data['arr2']

# 3. Save to CSV format:
# Save to CSV
np.savetxt('output.csv', arr, delimiter=',')

# CSV with custom options
np.savetxt('output.csv', arr, delimiter=',', fmt='%.2f', header='values')

# Load from CSV
loaded = np.loadtxt('output.csv', delimiter=',')

# 4. Memory-mapped arrays (for large arrays):
# Create memory-mapped array
mmapped = np.memmap('large_array.dat', dtype='float64', mode='w+', shape=(1000, 1000))
mmapped[:] = np.random.randn(1000, 1000)

# Load memory-mapped array
loaded_mmapped = np.memmap('large_array.dat', dtype='float64', mode='r', shape=(1000, 1000))

# 5. Save structured arrays:
dtype = [('id', 'i4'), ('value', 'f4')]
structured = np.array([(1, 1.5), (2, 2.5)], dtype=dtype)
np.save('structured.npy', structured)

# Load structured array
loaded_structured = np.load('structured.npy')

Troubleshooting & Best Practices | Common Issues | Performance Optimization | Best Practices

Common Issues

Array Creation Errors: Ensure input data is in correct format (lists, tuples). Check that all elements are compatible types. Verify array shape matches operations
Import Errors: Verify all dependencies installed: pip install -r requirements.txt. Check Python version (3.7+). Verify NumPy is installed: pip install numpy
Shape Mismatch Errors: Verify array shapes are compatible for operations. Check broadcasting rules. Use arr.shape to inspect array dimensions
Type Errors: Ensure numeric data types are correct. Use arr.dtype to check types. Convert types with arr.astype() if needed
File Loading Errors: Check file path is correct. Verify file format is supported (.npy, .npz, CSV, text). Check file exists and has proper permissions
Slow Performance: Use vectorized operations instead of Python loops. Leverage NumPy's universal functions (ufuncs). Use appropriate data types. Consider memory-mapped arrays for large data
Memory Issues: Use memory-mapped arrays (np.memmap) for large datasets. Use appropriate data types to reduce memory. Delete unused arrays. Check array size with arr.nbytes
Index Errors: Verify index values are within array bounds. Use arr.shape to check dimensions. Use proper slicing syntax
Broadcasting Errors: Verify array shapes are compatible for broadcasting. Check broadcasting rules. Use np.broadcast_arrays() to test compatibility
Save/Load Errors: Verify permissions to save files. Check file path is writable. Ensure directory exists. Use correct file extensions (.npy, .npz, .csv)
Linear Algebra Errors: Verify matrices are square for inversion. Check matrix dimensions match for multiplication. Ensure matrices are not singular for inversion
NaN/Inf Handling: Use np.isnan() and np.isinf() to detect invalid values. Use masked arrays for missing data. Replace invalid values appropriately

Performance Optimization Tips

Data Extracts: Create .hyper extracts for faster performance. Schedule regular extract refreshes
Data Filtering: Filter data at the source when possible. Use context filters for better performance
Calculated Fields: Optimize calculated field formulas. Use simpler calculations where possible. Cache frequently used calculations
Visualization Complexity: Limit number of marks in visualizations. Use aggregations before detail level
Data Preprocessing: Clean and validate data before analysis. Handle missing values appropriately
Data Validation: Check data types, missing values, and duplicates early in the process
Notebook Performance: Use appropriate data types. Avoid loading entire large datasets into memory at once
Code Organization: Break complex operations into smaller steps. Use functions for reusable code

Best Practices

Array Quality: Ensure arrays are created correctly with proper shapes and data types. Validate array contents before operations
Array Format: Always validate array shapes and data types before performing operations
Data Types: Use appropriate dtypes (int, float, complex) to balance precision and memory usage
Array Size: For large arrays (100K+ elements), use memory-mapped arrays or process in chunks for better performance
Code Style: Follow PEP 8 guidelines. Use meaningful variable names. Add comments for complex operations
Error Handling: Use try-except blocks for array operations. Validate arrays before processing
Array Validation: Always check array shapes, data types, and contents before analysis
Save Formats: Save arrays to .npy (native), .npz (compressed), or CSV formats for sharing and further analysis
Operation Types: Choose appropriate NumPy operations (vectorized operations, ufuncs, linear algebra) for better performance
Documentation: Document your code and array operations. Use markdown cells in Jupyter notebooks
Testing: Test your code with sample arrays before processing large datasets
Sharing: Share notebooks via Jupyter Notebook Viewer, GitHub, or export as HTML/PDF
