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 solve this problem, we will 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 content into 16 files (`/tmp/merged_%d` for `i` in `0..15`) so that each of the merged files is approximately the same size. Here is a step-by-step Python script to accomplish this task:
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 | import os # Read the list of file paths file_paths = [] with open('/tmp/files', 'r') as f: for line in f: file_paths.append(line.strip()) # Calculate the total size of all files total_size = 0 for file_path in file_paths: total_size += os.path.getsize(file_path) # Calculate the target size for each merged file target_size = total_size // 16 # Initialize the merged files merged_files = [] for i in range(16): merged_file_path = f'/tmp/merged_{i}' merged_files.append(open(merged_file_path, 'wb')) # Initialize the index of the current merged file current_file_index = 0 current_file_size = 0 # Merge the files for file_path in file_paths: with open(file_path, 'rb') as f: while True: chunk = f.read(4096) if not chunk: break # Write the chunk to the current merged file merged_files[current_file_index].write(chunk) current_file_size += len(chunk) # If the current merged file is full, move to the next one if current_file_size >= target_size and current_file_index < 15: current_file_index += 1 current_file_size = 0 # Close the merged files for f in merged_files: f.close() |
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 | import os # Read the list of file paths file_paths = [] with open('/tmp/files', 'r') as f: for line in f: file_paths.append(line.strip()) # Calculate the total size of all files total_size = 0 for file_path in file_paths: total_size += os.path.getsize(file_path) # Calculate the target size for each merged file target_size = total_size // 16 # Initialize the merged files merged_files = [] for i in range(16): merged_file_path = f'/tmp/merged_{i}' merged_files.append(open(merged_file_path, 'wb')) # Initialize the index of the current merged file current_file_index = 0 current_file_size = 0 # Merge the files for file_path in file_paths: with open(file_path, 'rb') as f: while True: chunk = f.read(4096) if not chunk: break # Write the chunk to the current merged file merged_files[current_file_index].write(chunk) current_file_size += len(chunk) # If the current merged file is full, move to the next one if current_file_size >= target_size and current_file_index < 15: current_file_index += 1 current_file_size = 0 # Close the merged files for f in merged_files: f.close() |
Running the following program:
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 | import os # Read the list of file paths file_paths = [] with open('/tmp/files', 'r') as f: for line in f: file_paths.append(line.strip()) # Calculate the total size of all files total_size = 0 for file_path in file_paths: total_size += os.path.getsize(file_path) # Calculate the target size for each merged file target_size = total_size // 16 # Initialize the merged files merged_files = [] for i in range(16): merged_file_path = f'/tmp/merged_{i}' merged_files.append(open(merged_file_path, 'wb')) # Initialize the index of the current merged file current_file_index = 0 current_file_size = 0 # Merge the files for file_path in file_paths: with open(file_path, 'rb') as f: while True: chunk = f.read(4096) if not chunk: break # Write the chunk to the current merged file merged_files[current_file_index].write(chunk) current_file_size += len(chunk) # If the current merged file is full, move to the next one if current_file_size >= target_size and current_file_index < 15: current_file_index += 1 current_file_size = 0 # Close the merged files for f in merged_files: f.close() |
final: False Resulting in output: False
