⚡ ROCm Version

This modified fork of Bittensor is 100% compatible with:

• ✅ PyTorch 2.4.0 ROCm
• ✅ ROCm 6.3.4 (multi-GPU AMD)
• ✅ Python 3.12
• ✅ Ubuntu 22.04 / Kernel 6.8+

🎯 Goal: Mine, validate, and explore Bittensor using an AMD ROCm rig – without CUDA or Docker dependencies.

---

🚨 BEFORE INSTALLING

You must install ROCm and PyTorch ROCm manually following this official guide:
👉 eliranwong/MultiAMDGPU_AIDev_Ubuntu

---

✅ Quick Installation

git clone https://github.com/Dev-next-gen/Bittensor-rocm.git
cd Bittensor-rocm
chmod +x install.sh
./install.sh
source venv/bin/activate

---

🧪 Verify Installation

python3 -c "import bittensor; print(bittensor.__version__)"
btcli wallet list

Expected output:

TORCH HIP ACTIVE: True
BITTENSOR OK: 2.0.0

---

✅ Features Maintained

• Fully working btcli
• TAO wallet coldkey & hotkey support
• RPC / Axon / Metagraph communication
• ROCm-based mining support
• Subnet registration & synchronization

---

🧪 ROCm Test Suite

We provide an isolated ROCm test suite to validate functionality without invoking CUDA:

pytest

Structure:

rocm_tests/
├── __init__.py
├── test_imports_rocm.py
├── test_rocm_env.py
└── test_pow_smoke_rocm.py

pytest.ini (at project root):

[pytest]
minversion = 6.0
addopts = -ra -q
testpaths = rocm_tests
python_files = test_*.py
norecursedirs = tests/unit_tests

---

🔥 Additional Step: Compile bittensor_helpers Extension (for ROCm)

Bittensor ROCm requires compiling a custom extension (bittensor_helpers) to enable GPU PoW solving.

Steps:

cd bittensor/_extensions
python setup.py clean --all
python setup.py build_ext --inplace
python setup.py install

If you encounter errors about libc10.so not found, please run:

export LD_LIBRARY_PATH=$(python -c 'import torch; import os; print(os.path.join(os.path.dirname(torch.__file__), "lib"))'):$LD_LIBRARY_PATH

(Make it permanent by adding it to your ~/.bashrc.)

✅ After compilation, you will be able to use ROCm GPU acceleration in Bittensor.

---

🛠️ CLI Wallet Management (btcli)

After installation, you can manage wallets directly using the CLI:

# List available wallets
btcli wallet list

# Create a new coldkey
btcli wallet new-coldkey --wallet.name YourWalletName

# Create a new hotkey
btcli wallet new-hotkey --wallet.name YourWalletName --wallet.hotkey YourHotkeyName

# Regenerate a coldkey if needed
btcli wallet regen-coldkey --wallet.name YourWalletName

---

🛠️ CLI Metagraph Management (btcli)

You can also synchronize and inspect the Bittensor Metagraph:

# Synchronize the Metagraph
btcli metagraph sync

# Overview the Metagraph
btcli metagraph overview

---

🧪 Wallet Management via Python

Example if you want to interact manually in Python:

from bittensor_wallet import Wallet

# Load existing wallet
wallet = Wallet(name="YourWalletName", hotkey="YourHotkeyName")

print(f"Coldkey Address: {wallet.coldkeypub.ss58_address}")
print(f"Hotkey Address: {wallet.hotkey.ss58_address}")

✅ Full coldkey/hotkey control directly in Python.
