Comment by Ross Wightman: This is the same as the DropConnect impl I created for EfficientNet, etc networks, however, the original name is misleading as 'Drop Connect' is a different form of dropout in a separate paper... See discussion: https://github.com/tensorflow/tpu/issues/494#issuecomment-532968956 ... I've opted for changing the layer and argument names to 'drop path' rather than mix DropConnect as a layer name and use 'survival rate' as the argument. rrr)r)rGdevice)rJndimr)randrGrfloor_div)rrr keep_probrJ random_tensorrs r: drop_pathrQsCx I I [[^  Q 7 7E 5 ELL YYM YYy !M 1F Mr;cxeZdZdZd deeddffd ZdejdejfdZ de fdZ xZ S) Dinov2DropPathzXDrop paths (Stochastic Depth) per sample (when applied in main path of residual blocks).Nrr$c0t|||_yri)r&r'r)r8rr9s r:r'zDinov2DropPath.__init__is "r;rcDt||j|jSri)rrr)r8rs r:rhzDinov2DropPath.forwardms FFr;c8dj|jS)Nzp={})formatrr8s r: extra_reprzDinov2DropPath.extra_reprps}}T^^,,r;ri) rjrkrlrmrfloatr'r)rnrhstrrrprqs@r:rrfsGb#(5/#T#GU\\GellG-C-r;rcXeZdZdfd Zdej dej fdZxZS) Dinov2MLPr$c~t||jx}}t|j|jz}t j ||d|_t|jtrt|j|_ n|j|_ t j ||d|_ y)NTr)r&r'r+ro mlp_ratior rfc1rx hidden_actrr activationfc2r8r# in_features out_featureshidden_featuresr9s r:r'zDinov2MLP.__init__us %+%7%77 lf0063C3CCD99[/E f'' -$V%6%67DO$//DO99_lFr;rcl|j|}|j|}|j|}|Sri)rrrrs r:rhzDinov2MLP.forwards2xx - |4 xx - r;rrrqs@r:rrts$ GELLU\\r;rcXeZdZdfd Zdej dej fdZxZS)Dinov2SwiGLUFFNr$c0t||jx}}t|j|jz}t|dzdz dzdzdz}t j |d|zd|_t j ||d|_y)NrArTr) r&r'r+rorr r weights_in weights_outrs r:r'zDinov2SwiGLUFFN.__init__s %+%7%77 lf0063C3CCD2Q67!;AAE))K_1D4P99_lNr;rc|j|}|jdd\}}tjj ||z}|j |S)NrAr@rH)rchunkr rOsilur)r8rx1x2hiddens r:rhzDinov2SwiGLUFFN.forwardsS|4 ##A2#.B##B'",''r;rrrqs@r:rrs$O(ELL(U\\(r;rc eZdZdZdeddffd Z d dejdeejde de e ejejfe ejffd Z xZ S) Dinov2LayerzCThis corresponds to the Block class in the original implementation.r#r$Nct|tj|j|j |_t||_t||_ |jdkDrt|jntj|_tj|j|j |_|j rt#||_nt'||_t||_y)Nepsr)r&r'r LayerNormr+layer_norm_epsnorm1rrr layer_scale1drop_path_raterIdentityrnorm2use_swiglu_ffnrmlpr layer_scale2rs r:r'zDinov2Layer.__init__s \\&"4"4&:O:OP (0,V4BHBWBWZ]B](=(=>cecncncp\\&"4"4&:O:OP  &v.DH (DH,V4r;rrrcD|j|j|||}|d}|j|}|dd}|j||z}|j |}|j |}|j |}|j||z}|f|z}|S)N)rrr)rrrrrrr)r8rrrself_attention_outputsrr layer_outputs r:rhzDinov2Layer.forwards "& JJ} % /"0"  2!4,,-=>(,'78=H zz-0 xx - ((6 ~~l3mC /G+r;r)rjrkrlrmr r'r)rnrrr rrhrprqs@r:r r s~M5|55&-1"' ||ELL)  uU\\5<</0% 2EE F r;r ceZdZdeddffd Z d dej deej deded ede e e ff d Z xZ S) Dinov2Encoderr#r$Nct|||_tjt |j Dcgc] }t|c}|_d|_ ycc}wr) r&r'r#r ModuleListrangenum_hidden_layersr layergradient_checkpointingr8r#rfr9s r:r'zDinov2Encoder.__init__sN  ]]vG_G_A`#aAK$7#ab &+#$bsA#rrroutput_hidden_states return_dictct|rdnd}|rdnd}t|jD]h\}} |r||fz}|||nd} |jr+|jr|j | j || |} n | || |} | d}|s`|| dfz}j|r||fz}|st d|||fDSt|||S)Nrrc3&K|] }|| ywrir)).0vs r: z(Dinov2Encoder.forward..smq_`_lms)last_hidden_stater attentions) enumerater#r$r_gradient_checkpointing_func__call__tupler) r8rrrr&r'all_hidden_statesall_self_attentionsi layer_modulelayer_head_mask layer_outputss r:rhzDinov2Encoder.forwards#7BD$5b4(4 POA|#$58H$H!.7.CilO**t}} $ A A ))!#% ! !-]OM^ _ )!,M &9]1=M
