+:::info Machine Learning on older CPU
+
+TensorFlow doesn't run with older CPU architecture, it requires a CPU with AVX and AVX2 instruction set. If you encounter the error `illegal instruction core dump` check for your CPU flags with the command and make sure you see `AVX` and `AVX2`:
+
+```bash
+more /proc/cpuinfo | grep flags
+```
+
+#### Promox
+
+If you are running virtualization in Proxmox, the VM doesn't have the flag enabled.
+
+You need to change the CPU type from `kvm64` to `host` under VMs hardware tab.
+
+`Hardware > Processors > Edit > Advanced > Type (dropdown menu) > host`
+
+#### Other platforms
+
+You can use the machine learning image that is built for Non-AVX CPU. The image is community maintained and can be found in the repository below
