## Masuala ya Usakinishaji

### Usakinishaji wa Python

**Tatizo**: `python: command not found`

**Suluhisho**:
1. Sakinisha Python 3.8 au toleo la juu zaidi kutoka [python.org](https://www.python.org/downloads/)
2. Thibitisha usakinishaji: `python --version` au `python3 --version`
3. Kwenye macOS/Linux, huenda ukahitaji kutumia `python3` badala ya `python`

**Tatizo**: Matoleo mengi ya Python yanayosababisha migongano

**Suluhisho**:
```bash
# Use virtual environments to isolate projects
python -m venv ml-env

# Activate virtual environment
# On Windows:
ml-env\Scripts\activate
# On macOS/Linux:
source ml-env/bin/activate
```

### Usakinishaji wa Jupyter

**Tatizo**: `jupyter: command not found`

**Suluhisho**:
```bash
# Install Jupyter
pip install jupyter

# Or with pip3
pip3 install jupyter

# Verify installation
jupyter --version
```

**Tatizo**: Jupyter haifunguki kwenye kivinjari

**Suluhisho**:
```bash
# Try specifying the browser
jupyter notebook --browser=chrome

# Or copy the URL with token from terminal and paste in browser manually
# Look for: http://localhost:8888/?token=...
```

### Usakinishaji wa R

**Tatizo**: Vifurushi vya R havisakinishwi

**Suluhisho**:
```r
# Ensure you have the latest R version
# Install packages with dependencies
install.packages(c("tidyverse", "tidymodels", "caret"), dependencies = TRUE)

# If compilation fails, try installing binary versions
install.packages("package-name", type = "binary")
```

**Tatizo**: IRkernel haipatikani kwenye Jupyter

**Suluhisho**:
```r
# In R console
install.packages('IRkernel')
IRkernel::installspec(user = TRUE)
```

---

## Masuala ya Jupyter Notebook

### Masuala ya Kernel

**Tatizo**: Kernel inazima au kuanzisha upya mara kwa mara

**Suluhisho**:
1. Anzisha upya kernel: `Kernel → Restart`
2. Futa matokeo na uanzishe upya: `Kernel → Restart & Clear Output`
3. Angalia masuala ya kumbukumbu (tazama [Masuala ya Utendaji](../..))
4. Jaribu kuendesha seli moja moja ili kubaini msimbo wenye tatizo

**Tatizo**: Kernel isiyo sahihi imechaguliwa

**Suluhisho**:
1. Angalia kernel ya sasa: `Kernel → Change Kernel`
2. Chagua toleo sahihi la Python
3. Ikiwa kernel haipo, tengeneza:
```bash
python -m ipykernel install --user --name=ml-env
```

**Tatizo**: Kernel haianzi

**Suluhisho**:
```bash
# Reinstall ipykernel
pip uninstall ipykernel
pip install ipykernel

# Register the kernel again
python -m ipykernel install --user
```

### Masuala ya Seli za Notebook

**Tatizo**: Seli zinaendesha lakini hazionyeshi matokeo

**Suluhisho**:
1. Angalia ikiwa seli bado inaendesha (angalia kiashiria cha `[*]`)
2. Anzisha upya kernel na uendeshe seli zote: `Kernel → Restart & Run All`
3. Angalia console ya kivinjari kwa makosa ya JavaScript (F12)

**Tatizo**: Seli haziwezi kuendeshwa - hakuna majibu unapobofya "Run"

**Suluhisho**:
1. Angalia ikiwa seva ya Jupyter bado inaendesha kwenye terminal
2. Pakia upya ukurasa wa kivinjari
3. Funga na ufungue tena notebook
4. Anzisha upya seva ya Jupyter

## Masuala ya Vifurushi vya Python

### Makosa ya Uingizaji

**Tatizo**: `ModuleNotFoundError: No module named 'sklearn'`

**Suluhisho**:
```bash
pip install scikit-learn

# Common ML packages for this course
pip install scikit-learn pandas numpy matplotlib seaborn
```

**Tatizo**: `ImportError: cannot import name 'X' from 'sklearn'`

**Suluhisho**:
```bash
# Update scikit-learn to latest version
pip install --upgrade scikit-learn

# Check version
python -c "import sklearn; print(sklearn.__version__)"
```

### Migongano ya Matoleo

**Tatizo**: Makosa ya kutokubaliana kwa matoleo ya vifurushi

**Suluhisho**:
```bash
# Create a new virtual environment
python -m venv fresh-env
source fresh-env/bin/activate  # or fresh-env\Scripts\activate on Windows

# Install packages fresh
pip install jupyter scikit-learn pandas numpy matplotlib seaborn

# If specific version needed
pip install scikit-learn==1.3.0
```

**Tatizo**: `pip install` inashindwa kwa makosa ya ruhusa

**Suluhisho**:
```bash
# Install for current user only
pip install --user package-name

# Or use virtual environment (recommended)
python -m venv venv
source venv/bin/activate
pip install package-name
```

### Masuala ya Kupakia Data

**Tatizo**: `FileNotFoundError` wakati wa kupakia faili za CSV

**Suluhisho**:
```python
import os
# Check current working directory
print(os.getcwd())

# Use relative paths from notebook location
df = pd.read_csv('../../data/filename.csv')

# Or use absolute paths
df = pd.read_csv('/full/path/to/data/filename.csv')
```

---

## Masuala ya Mazingira ya R

### Usakinishaji wa Vifurushi

**Tatizo**: Usakinishaji wa kifurushi unashindwa kwa makosa ya uundaji

**Suluhisho**:
```r
# Install binary version (Windows/macOS)
install.packages("package-name", type = "binary")

# Update R to latest version if packages require it
# Check R version
R.version.string

# Install system dependencies (Linux)
# For Ubuntu/Debian, in terminal:
# sudo apt-get install r-base-dev
```

**Tatizo**: `tidyverse` haisakinishwi

**Suluhisho**:
```r
# Install dependencies first
install.packages(c("rlang", "vctrs", "pillar"))

# Then install tidyverse
install.packages("tidyverse")

# Or install components individually
install.packages(c("dplyr", "ggplot2", "tidyr", "readr"))
```

### Masuala ya RMarkdown

**Tatizo**: RMarkdown haionyeshi

**Suluhisho**:
```r
# Install/update rmarkdown
install.packages("rmarkdown")

# Install pandoc if needed
install.packages("pandoc")

# For PDF output, install tinytex
install.packages("tinytex")
tinytex::install_tinytex()
```

---

## Masuala ya Programu ya Maswali

### Ujenzi na Usakinishaji

**Tatizo**: `npm install` inashindwa

**Suluhisho**:
```bash
# Clear npm cache
npm cache clean --force

# Remove node_modules and package-lock.json
rm -rf node_modules package-lock.json

# Reinstall
npm install

# If still fails, try with legacy peer deps
npm install --legacy-peer-deps
```

**Tatizo**: Bandari 8080 tayari inatumika

**Suluhisho**:
```bash
# Use different port
npm run serve -- --port 8081

# Or find and kill process using port 8080
# On Linux/macOS:
lsof -ti:8080 | xargs kill -9

# On Windows:
netstat -ano | findstr :8080
taskkill /PID <PID> /F
```

### Makosa ya Ujenzi

**Tatizo**: `npm run build` inashindwa

**Suluhisho**:
```bash
# Check Node.js version (should be 14+)
node --version

# Update Node.js if needed
# Then clean install
rm -rf node_modules package-lock.json
npm install
npm run build
```

**Tatizo**: Makosa ya linting yanazuia ujenzi

**Suluhisho**:
```bash
# Fix auto-fixable issues
npm run lint -- --fix

# Or temporarily disable linting in build
# (not recommended for production)
```

---

## Masuala ya Data na Njia za Faili

### Masuala ya Njia

**Tatizo**: Faili za data hazipatikani wakati wa kuendesha notebooks

**Suluhisho**:
1. **Daima endesha notebooks kutoka kwenye folda yake**
   ```bash
   cd /path/to/lesson/folder
   jupyter notebook
   ```

2. **Angalia njia za jamaa kwenye msimbo**
   ```python
   # Correct path from notebook location
   df = pd.read_csv('../data/filename.csv')
   
   # Not from your terminal location
   ```

3. **Tumia njia kamili ikiwa inahitajika**
   ```python
   import os
   base_path = os.path.dirname(os.path.abspath(__file__))
   data_path = os.path.join(base_path, 'data', 'filename.csv')
   ```

### Faili za Data Zinazokosekana

**Tatizo**: Faili za dataset zinakosekana

**Suluhisho**:
1. Angalia ikiwa data inapaswa kuwa kwenye hifadhi - datasets nyingi zimejumuishwa
2. Masomo mengine yanaweza kuhitaji kupakua data - angalia README ya somo
3. Hakikisha umepakua mabadiliko ya hivi karibuni:
   ```bash
   git pull origin main
   ```

## Ujumbe wa Makosa ya Kawaida

### Makosa ya Kumbukumbu

**Kosa**: `MemoryError` au kernel inakufa wakati wa kuchakata data

**Suluhisho**:
```python
# Load data in chunks
for chunk in pd.read_csv('large_file.csv', chunksize=10000):
    process(chunk)

# Or read only needed columns
df = pd.read_csv('file.csv', usecols=['col1', 'col2'])

# Free memory when done
del large_dataframe
import gc
gc.collect()
```

### Onyo la Mkutano

**Onyo**: `ConvergenceWarning: Maximum number of iterations reached`

**Suluhisho**:
```python
from sklearn.linear_model import LogisticRegression

# Increase max iterations
model = LogisticRegression(max_iter=1000)

# Or scale your features first
from sklearn.preprocessing import StandardScaler
scaler = StandardScaler()
X_scaled = scaler.fit_transform(X)
```

### Masuala ya Kuchora Michoro

**Tatizo**: Michoro haionyeshwi kwenye Jupyter

**Suluhisho**:
```python
# Enable inline plotting
%matplotlib inline

# Import pyplot
import matplotlib.pyplot as plt

# Show plot explicitly
plt.plot(data)
plt.show()
```

**Tatizo**: Michoro ya Seaborn inaonekana tofauti au inatoa makosa

**Suluhisho**:
```python
import warnings
warnings.filterwarnings('ignore', category=UserWarning)

# Update to compatible version
# pip install --upgrade seaborn matplotlib
```

### Makosa ya Unicode/Kodifikesheni

**Tatizo**: `UnicodeDecodeError` wakati wa kusoma faili

**Suluhisho**:
```python
# Specify encoding explicitly
df = pd.read_csv('file.csv', encoding='utf-8')

# Or try different encoding
df = pd.read_csv('file.csv', encoding='latin-1')

# For errors='ignore' to skip problematic characters
df = pd.read_csv('file.csv', encoding='utf-8', errors='ignore')
```

---

## Masuala ya Utendaji

### Utekelezaji Polepole wa Notebook

**Tatizo**: Notebooks zinaendesha polepole sana

**Suluhisho**:
1. **Anzisha upya kernel ili kuachilia kumbukumbu**: `Kernel → Restart`
2. **Funga notebooks zisizotumika** ili kuachilia rasilimali
3. **Tumia sampuli ndogo za data kwa majaribio**:
   ```python
   # Work with subset during development
   df_sample = df.sample(n=1000)
   ```
4. **Pima msimbo wako** ili kubaini sehemu zenye matatizo:
   ```python
   %time operation()  # Time single operation
   %timeit operation()  # Time with multiple runs
   ```

### Matumizi Makubwa ya Kumbukumbu

**Tatizo**: Mfumo unakosa kumbukumbu

**Suluhisho**:
```python
# Check memory usage
df.info(memory_usage='deep')

# Optimize data types
df['column'] = df['column'].astype('int32')  # Instead of int64

# Drop unnecessary columns
df = df[['col1', 'col2']]  # Keep only needed columns

# Process in batches
for batch in np.array_split(df, 10):
    process(batch)
```

---

## Mazingira na Usanidi

### Masuala ya Mazingira ya Kawaida

**Tatizo**: Mazingira ya kawaida hayafanyi kazi

**Suluhisho**:
```bash
# Windows
python -m venv venv
venv\Scripts\activate.bat

# macOS/Linux
python3 -m venv venv
source venv/bin/activate

# Check if activated (should show venv name in prompt)
which python  # Should point to venv python
```

**Tatizo**: Vifurushi vimesakinishwa lakini havipatikani kwenye notebook

**Suluhisho**:
```bash
# Ensure notebook uses the correct kernel
# Install ipykernel in your venv
pip install ipykernel
python -m ipykernel install --user --name=ml-env --display-name="Python (ml-env)"

# In Jupyter: Kernel → Change Kernel → Python (ml-env)
```

### Masuala ya Git

**Tatizo**: Huwezi kupakua mabadiliko ya hivi karibuni - migogoro ya kuunganisha

**Suluhisho**:
```bash
# Stash your changes
git stash

# Pull latest
git pull origin main

# Reapply your changes
git stash pop

# If conflicts, resolve manually or:
git checkout --theirs path/to/file  # Take remote version
git checkout --ours path/to/file    # Keep your version
```

### Ushirikiano wa VS Code

**Tatizo**: Jupyter notebooks hazifunguki kwenye VS Code

**Suluhisho**:
1. Sakinisha kiendelezi cha Python kwenye VS Code
2. Sakinisha kiendelezi cha Jupyter kwenye VS Code
3. Chagua tafsiri sahihi ya Python: `Ctrl+Shift+P` → "Python: Select Interpreter"
4. Anzisha upya VS Code
