There was a problem hiding this comment. 这个session_ctx一旦初始化就不会被修改是吗？ There was a problem hiding this comment. 这里稍稍有点反直觉。我一直以为是session_ctx持有oneflow_env。 There was a problem hiding this comment. 是的，这里是 serving的用法，看起来serving那里目前是这么设定的。 session_ctx_会持有env_ctx_；oneflow_env包括了env和session，是导出给serving做oneflow总体启动和关闭的，之前的命名直接是env，这里沿袭了一下，叫oneflow env。 |
