38
+ ## πŸš€ Quick Start Guide
39
+
40
+ **New to this model? Start here!**
41
+
42
+ ### Option 1: Load from Hugging Face Hub (Recommended)
43
+ ```python
44
+ # Install required packages first
45
+ # pip install transformers torch
46
+
47
+ from transformers import AutoTokenizer, AutoModelForCausalLM
48
+
49
+ # Load the model
50
+ tokenizer = AutoTokenizer.from_pretrained("likhonsheikh/prothom-alo-model")
51
+ model = AutoModelForCausalLM.from_pretrained("likhonsheikh/prothom-alo-model")
52
+
53
+ # Generate text
54
+ prompt = "The latest news from Bangladesh"
55
+ inputs = tokenizer(prompt, return_tensors="pt")
56
+ outputs = model.generate(**inputs, max_length=100, do_sample=True, temperature=0.8)
57
+ generated_text = tokenizer.decode(outputs[0], skip_special_tokens=True)
58
+ print("Generated:", generated_text)
59
+ ```
60
+
61
+ ### Option 2: Use with Pipeline (Easiest)
62
+ ```python
63
+ from transformers import pipeline
64
+
65
+ # Create a text generation pipeline
66
+ generator = pipeline('text-generation', model='likhonsheikh/prothom-alo-model')
67
+
68
+ # Generate news-style content
69
+ result = generator("Today's news from Bangladesh", max_length=150, temperature=0.8)
70
+ print(result[0]['generated_text'])
71
+ ```
72
+
73
+ ### Option 3: Direct Safetensors Loading
74
+ ```python
75
+ # For advanced users who need direct tensor access
76
+ from safetensors import safe_open
77
+ import torch
78
+
79
+ with safe_open("https://huggingface.co/likhonsheikh/prothom-alo-model/resolve/main/prothomalo_model.safetensors",
80
+ framework="pt", device=0) as f:
81
+ print(f"Model tensors: {len(f.keys())}")
82
+ # Access any tensor you need
83
+ embedding = f.get_tensor("transformer.wte.weight")
84
+ print(f"Embedding shape: {embedding.shape}")

+ ## πŸ”§ Troubleshooting Guide
332
+
333
+ ### Common Issues & Solutions
334
+
335
+ **Problem: "CUDA out of memory"**
336
+ ```python
337
+ # Solution: Use gradient checkpointing and smaller batch
338
+ model.gradient_checkpointing_enable()
339
+ # Or use CPU
340
+ model = AutoModelForCausalLM.from_pretrained("likhonsheikh/prothom-alo-model", device_map="cpu")
341
+ ```
342
+
343
+ **Problem: Slow generation**
344
+ ```python
345
+ # Solution: Use pipeline with device optimization
346
+ from transformers import pipeline
347
+ generator = pipeline('text-generation', model='likhonsheikh/prothom-alo-model', device=0) # GPU
348
+ ```
349
+
350
+ **Problem: Repetitive output**
351
+ ```python
352
+ # Solution: Increase repetition penalty
353
+ outputs = model.generate(
354
+ **inputs,
355
+ repetition_penalty=1.3, # Higher value reduces repetition
356
+ temperature=0.8
357
+ )
358
+ ```
359
+
360
+ **Problem: "Module not found"**
361
+ ```bash
362
+ # Solution: Install dependencies
363
+ pip install --upgrade transformers torch safetensors

479
+ model = AutoModelForCausalLM.from_pretrained("./prothomalo_model/final_model")
480
+
481
+ # Generate text
482
+ prompt = "The latest news from Bangladesh"
483
+ inputs = tokenizer(prompt, return_tensors="pt")
484
+ outputs = model.generate(**inputs, max_length=150, do_sample=True, temperature=0.8)
485

496
+ with safe_open("prothomalo_model.safetensors", framework="pt", device=0) as f:
497
+ print(f"Available tensors: {len(f.keys())}")
498
+ for key in list(f.keys())[:5]: # Show first 5 keys
499
