+# Python Virtual Environment Setup Guide for Buddy-mlir
+
+We recommend you to use anaconda3 to create python virtual environment. You should install python packages as buddy-mlir/requirements.
+
+```bash
+$ conda create -n <your virtual environment name> python=3.11
+$ conda activate <your virtual environment name>
+$ cd buddy-mlir
+$ pip install -r requirements.txt
+```
