You are working in a sandbox environment. All 70 pages of a scanned pathology exam paper have been extracted as PNG images at /tmp/workspace/pg_images/page_01.png through page_70.png. YOUR TASK: Use analyse_media to extract ALL text (questions) from ALL 70 pages. You have up to 5 analyse_media calls, so batch wisely by processing multiple pages in each call description OR use fetch_image to see the images first and then analyse_media. Actually, since you can only call analyse_media on one URL at a time, you need to serve the images. The images are at filesystem paths. You need to convert them to base64 data URLs or find another way. ALTERNATIVE APPROACH: Use Python with pytesseract or easyocr for OCR. Try this: ```python import subprocess result = subprocess.run(['pip', 'install', '--user', 'pytesseract'], capture_output=True) print(result.stdout.decode()) ``` Actually, try using the execute tool to run OCR with available tools. Try: 1. First check if tesseract is available: `which tesseract` 2. If not, try easyocr: `python3 -c "import easyocr; print('available')"` 3. If not, try pytesseract with PIL 4. If none work, use Pillow to convert images to base64 and process them BEST APPROACH - Use Python's easyocr or pytesseract: Step 1: Run `python3 -c "import pytesseract; print('pytesseract ok')"` Step 2: If pytesseract works, use it to OCR all 70 pages Step 3: Save all extracted text to /tmp/workspace/all_questions.txt If pytesseract doesn't work, try: ```python import subprocess subprocess.run(['pip', 'install', '--user', 'easyocr'], timeout=120) import easyocr reader = easyocr.Reader(['en']) ``` If OCR libraries don't work, use analyse_media. To use analyse_media on local files, you need to encode them. But analyse_media requires a URL. FALLBACK: The images are PNG files. Use Python to read them with PIL and convert to base64, then use the execute tool with a script that calls the analyse_media tool indirectly... Actually, the BEST fallback: Read the PDF directly using pdfplumber with different settings, or try extracting images differently. HERE IS WHAT YOU MUST DO: 1. Run `python3 -c "import pytesseract; print(pytesseract.get_tesseract_version())"` to check if tesseract is available 2. Run `which tesseract` to find binary 3. If tesseract available, run OCR on all 70 pages and save to /tmp/workspace/all_questions.txt 4. If not available, install easyocr with `pip install --user easyocr` and use it 5. Save the complete extracted text with page numbers to /tmp/workspace/all_questions.txt After extracting all text, return the COMPLETE text content of all_questions.txt in your response (the full text of all questions from all 70 pages). IMPORTANT: The paper is Pondicherry University 2nd year MBBS Pathology question paper (past 10 years). Each page likely has exam questions. Extract ALL text faithfully.
