Original GitHub issue: https://github.com/deepseek-ai/DeepGEMM/issues/306

Thank you for your marvelous work! i've been trying to test the mega_moe kernel , and encountered an error about deepep:

ep_buffer = deep_ep.ElasticBuffer(
                ^^^^^^^^^^^^^^^^^^^^^
AttributeError: module 'deep_ep' has no attribute 'ElasticBuffer'

And I found that there's no ElasticBuffer in the latest DeepEP... Could you please give the version of DeepEP for the kernel? Many many thanks!

Thank you for your kind words and for testing the mega_moe kernel!

The ElasticBuffer class is indeed a new feature introduced in DeepEP v2. The latest DeepEP release (v2) includes this API, but the older version does not. Please make sure you install the correct version — you can find it at the link you mentioned: DeepEP v2. After updating, the error should be resolved.
