+- run `git clone https://github.com/deepseek-ai/DeepSeek-VL2 repositories/deepseek-vl2 --depth 1`
+- remove hardcoded `python==3.9` requirement due to obsolete attrdict package dependency
+- patch transformers due to internal changes as deepseek requires obsolete `transformers==4.38.2`
+- deepseek requires `xformers`
+- broken flash_attention
