I have setup the docker container to run the model evaluation.
I have a list of several thousand file paths in /tmp/files. Write a python script that merges the content int 16 files called /tmp/merged_%d for i in 0..15 where each is approximately the same size. "/tmp/files" is a list of file paths, one per line.
I have a list of several thousand file paths in /tmp/files. Write a python script that merges the content int 16 files called /tmp/merged_%d for i in 0..15 where each is approximately the same size. "/tmp/files" is a list of file paths, one per line.
To achieve this, you can write a Python script that reads the list of file paths from `/tmp/files`, calculates the total size of all files, and then distributes the files into 16 output files (`/tmp/merged_0` to `/tmp/merged_15`) such that each output file has approximately the same total size. Here’s a Python script that does this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 | import os def get_file_size(file_path): """Returns the size of the file in bytes.""" return os.path.getsize(file_path) def distribute_files(file_paths, num_output_files): """Distributes files into output files such that each output file has approximately the same total size.""" # Calculate the total size of all files total_size = sum(get_file_size(path) for path in file_paths) # Calculate the target size for each output file target_size = total_size / num_output_files # Initialize variables output_files = [open(f'/tmp/merged_{i}', 'wb') for i in range(num_output_files)] current_sizes = [0] * num_output_files current_file_index = 0 # Distribute files for file_path in file_paths: file_size = get_file_size(file_path) # Find the output file with the smallest current size current_file_index = current_sizes.index(min(current_sizes)) # Write the file content to the selected output file with open(file_path, 'rb') as input_file: output_files[current_file_index].write(input_file.read()) # Update the current size of the selected output file current_sizes[current_file_index] += file_size # Close all output files for output_file in output_files: output_file.close() def main(): # Read the list of file paths from /tmp/files with open('/tmp/files', 'r') as file_list: file_paths = [line.strip() for line in file_list if line.strip()] # Distribute the files into 16 output files distribute_files(file_paths, 16) if __name__ == "__main__": main() |
1 2 | python3 merge_files.py |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 | import os def get_file_size(file_path): """Returns the size of the file in bytes.""" return os.path.getsize(file_path) def distribute_files(file_paths, num_output_files): """Distributes files into output files such that each output file has approximately the same total size.""" # Calculate the total size of all files total_size = sum(get_file_size(path) for path in file_paths) # Calculate the target size for each output file target_size = total_size / num_output_files # Initialize variables output_files = [open(f'/tmp/merged_{i}', 'wb') for i in range(num_output_files)] current_sizes = [0] * num_output_files current_file_index = 0 # Distribute files for file_path in file_paths: file_size = get_file_size(file_path) # Find the output file with the smallest current size current_file_index = current_sizes.index(min(current_sizes)) # Write the file content to the selected output file with open(file_path, 'rb') as input_file: output_files[current_file_index].write(input_file.read()) # Update the current size of the selected output file current_sizes[current_file_index] += file_size # Close all output files for output_file in output_files: output_file.close() def main(): # Read the list of file paths from /tmp/files with open('/tmp/files', 'r') as file_list: file_paths = [line.strip() for line in file_list if line.strip()] # Distribute the files into 16 output files distribute_files(file_paths, 16) if __name__ == "__main__": main() |
