# 🔍 Debugging Hugging Face Spaces Deployment
|

|

## Częste Problemy i Rozwiązania
|
| 4 |
+
|
| 5 |
+
### Problem 1: Runtime Error - Exit code: 0
|
| 6 |
+
**Objawy:**
|
| 7 |
+
```
|
| 8 |
+
Container logs:
|
| 9 |
+
===== Application Startup at 2025-12-13 12:09:26 =====
|
| 10 |
+
2025-12-13 13:09:40.467 | INFO | __main__:<module>:161 - 🚀 Starting Gradio app...
|
| 11 |
+
[aplikacja się zawiesza]
|
| 12 |
+
```
|
| 13 |
+
|
| 14 |
+
**Przyczyny:**
|
| 15 |
+
1. **Podwójny start aplikacji** - HF Spaces uruchamia aplikację dwukrotnie podczas budowy kontenera
|
| 16 |
+
2. **Blokada na połączeniu z bazą danych** - Próba zapisu do LanceDB bez uprawnień
|
| 17 |
+
3. **Brak API key** - Walidacja konfiguracji blokuje inicjalizację
|
| 18 |
+
4. **Timeout** - Inicjalizacja trwa zbyt długo (>60s)
|
| 19 |
+
|
| 20 |
+
**Rozwiązania zastosowane w projekcie:**
|
| 21 |
+
|
| 22 |
+
#### 1. Leniwą inicjalizację połączenia z bazą
|
| 23 |
+
```python
|
| 24 |
+
# ❌ PRZED - blokujące połączenie
|
| 25 |
+
vector_store = VectorStoreClient(uri="./lancedb")
|
| 26 |
+
vector_store.connect() # Blokuje na HF Spaces!
|
| 27 |
+
|
| 28 |
+
# ✅ PO - leniwe połączenie
|
| 29 |
+
vector_store = VectorStoreClient(uri="./lancedb")
|
| 30 |
+
# Połączenie następuje przy pierwszym użyciu
|
| 31 |
+
```
|
| 32 |
+
|
| 33 |
+
#### 2. Warunkową walidację API key
|
| 34 |
+
```python
|
| 35 |
+
@field_validator("openai_api_key")
|
| 36 |
+
@classmethod
|
| 37 |
+
def validate_api_key(cls, v):
|
| 38 |
+
v = v or ""
|
| 39 |
+
v = v.strip()
|
| 40 |
+
if not v:
|
| 41 |
+
# Nie rzucaj błędu na HF Spaces
|
| 42 |
+
if not os.getenv("SPACE_ID"):
|
| 43 |
+
raise ValueError("OPENAI_API_KEY is required")
|
| 44 |
+
return v
|
| 45 |
+
```
|
| 46 |
+
|
| 47 |
+
#### 3. Timeout dla inicjalizacji agenta
|
| 48 |
+
```python
|
| 49 |
+
def initialize_agent_background():
|
| 50 |
+
"""Inicjalizacja z 30-sekundowym timeoutem."""
|
| 51 |
+
def timeout_handler(signum, frame):
|
| 52 |
+
raise TimeoutError("Timeout after 30 seconds")
|
| 53 |
+
|
| 54 |
+
if hasattr(signal, 'SIGALRM'):
|
| 55 |
+
signal.signal(signal.SIGALRM, timeout_handler)
|
| 56 |
+
signal.alarm(30)
|
| 57 |
+
|
| 58 |
+
agent_instance = create_agent()
|
| 59 |
+
|
| 60 |
+
if hasattr(signal, 'SIGALRM'):
|
| 61 |
+
signal.alarm(0)
|
| 62 |
+
```
|
| 63 |
+
|
| 64 |
+
#### 4. Bezpieczne tworzenie katalogów
|
| 65 |
+
```python
|
| 66 |
+
@property
|
| 67 |
+
def db(self):
|
| 68 |
+
if self._db is None:
|
| 69 |
+
try:
|
| 70 |
+
os.makedirs(self.uri, exist_ok=True)
|
| 71 |
+
except Exception as e:
|
| 72 |
+
logger.warning(f"Could not create directory: {e}")
|
| 73 |
+
|
| 74 |
+
self._db = lancedb.connect(self.uri)
|
| 75 |
+
return self._db
|
| 76 |
+
```
|
| 77 |
+
|
| 78 |
+
### Problem 2: Aplikacja startuje ale nie odpowiada
|
| 79 |
+
|
| 80 |
+
**Przyczyna:** Agent nie zainicjalizował się w tle
|
| 81 |
+
|
| 82 |
+
**Rozwiązanie:**
|
| 83 |
+
- Sprawdź logi w HF Spaces - szukaj `✅ A11y Expert Agent is ready!`
|
| 84 |
+
- Jeśli brak, sprawdź czy nie ma błędu inicjalizacji
|
| 85 |
+
- Aplikacja pokazuje status inicjalizacji w interfejsie
|
| 86 |
+
|
| 87 |
+
### Problem 3: Brak dostępu do bazy danych
|
| 88 |
+
|
| 89 |
+
**Przyczyna:** Katalog `lancedb/` nie jest w repozytorium lub nie jest śledzony przez Git LFS
|
| 90 |
+
|
| 91 |
+
**Rozwiązanie:**
|
| 92 |
+
```bash
|
| 93 |
+
# Sprawdź czy lancedb jest w repo
|
| 94 |
+
git lfs ls-files | grep lancedb
|
| 95 |
+
|
| 96 |
+
# Jeśli nie, dodaj do LFS
|
| 97 |
+
git lfs track "lancedb/**"
|
| 98 |
+
git add .gitattributes lancedb/
|
| 99 |
+
git commit -m "Add LanceDB to LFS"
|
| 100 |
+
git push
|
| 101 |
+
```
|
| 102 |
+
|
| 103 |
+
### Problem 4: API Key nie jest ustawiony
|
| 104 |
+
|
| 105 |
+
**Objawy:**
|
| 106 |
+
```
|
| 107 |
+
❌ Failed to initialize agent: OPENAI_API_KEY is required
|
| 108 |
+
```
|
| 109 |
+
|
| 110 |
+
**Rozwiązanie:**
|
| 111 |
+
1. Idź do ustawień swojego Space
|
| 112 |
+
2. Wybierz zakładkę **Settings** → **Repository secrets**
|
| 113 |
+
3. Dodaj secret `OPENAI_API_KEY` z wartością twojego klucza
|
| 114 |
+
4. Zrestartuj Space
|
| 115 |
+
|
| 116 |
+
## Testowanie lokalne przed wdrożeniem
|
| 117 |
+
|
| 118 |
+
```bash
|
| 119 |
+
# Test wszystkich komponentów
|
| 120 |
+
python test_startup.py
|
| 121 |
+
|
| 122 |
+
# Test aplikacji Gradio
|
| 123 |
+
python app.py
|
| 124 |
+
```
|
| 125 |
+
|
| 126 |
+
## Sprawdzanie logów na HF Spaces
|
| 127 |
+
|
| 128 |
+
1. **Podczas budowy:**
|
| 129 |
+
- Kliknij na swój Space
|
| 130 |
+
- Przejdź do zakładki **Logs**
|
| 131 |
+
- Szukaj błędów podczas `Building` i `Running`
|
| 132 |
+
|
| 133 |
+
2. **Podczas działania:**
|
| 134 |
+
- Logi są na żywo w zakładce **Logs**
|
| 135 |
+
- Szukaj komunikatów ERROR lub stacktrace'ów
|
| 136 |
+
|
| 137 |
+
## Debugowanie z kodem
|
| 138 |
+
|
| 139 |
+
### Dodaj więcej logowania:
|
| 140 |
+
```python
|
| 141 |
+
import traceback
|
| 142 |
+
try:
|
| 143 |
+
# twój kod
|
| 144 |
+
except Exception as e:
|
| 145 |
+
logger.error(f"Error: {e}")
|
| 146 |
+
logger.error(traceback.format_exc())
|
| 147 |
+
```
|
| 148 |
+
|
| 149 |
+
### Sprawdź zmienne środowiskowe:
|
| 150 |
+
```python
|
| 151 |
+
import os
|
| 152 |
+
logger.info(f"SPACE_ID: {os.getenv('SPACE_ID')}")
|
| 153 |
+
logger.info(f"HF environment: {os.getenv('SYSTEM')}")
|
| 154 |
+
```
|
| 155 |
+
|
| 156 |
+
