Hinton. and centered version `Generating Sequences With Recurrent Neural Networks `_. The implementation here takes the square root of the gradient average before adding epsilon (note that TensorFlow interchanges these two operations). The effective learning rate is thus :math:`\gamma/(\sqrt{v} + \epsilon)` where :math:`\gamma` is the scheduled learning rate and :math:`v` is the weighted moving average of the squared gradient. z Args: a0 lr (float, Tensor, optional): learning rate (default: 1e-2) alpha (float, optional): smoothing constant (default: 0.99) eps (float, optional): term added to the denominator to improve numerical stability (default: 1e-8) weight_decay (float, optional): weight decay (L2 penalty) (default: 0) momentum (float, optional): momentum factor (default: 0) centered (bool, optional) : if ``True``, compute the centered RMSProp, the gradient is normalized by an estimation of its variance z z rrTrUrWrVrXrrrrrrr!r"rrYr#c "[RR5(d [U5n[ U5GHQunnUUn[R R 5(dhU(aa[5nURRURR:XaURRU;d[SUS35eUUnU (dUOU*nUUnUS- nU S:waURUU S9n[R"U5nU(aB[R"U5n[R"U5n[R"U5nURU5RUUSU- S9 U (aWUUnU(a[R"U5nUR!USU- 5 UR#UUSS9R%5nOUR'5nU (aURU5nOUR)U5nU S:aWUUnU(a[R"U5nURU 5R+UU5 UR)UU*S9 GM?UR+UUU*S9 GMT g)NIIf capturable=True, params and state_steps must be on supported devices: .rrrvalue)r<jit is_scriptingr enumeratecompiler is_compilingr r4typeAssertionErroraddrL view_as_realmul_addcmul_lerp_addcmulsqrt_sqrtadd_addcdiv_)rrTrUrWrVrXrrrrrrr!r"rrYiparamr1capturable_supported_devicesrKrHis_complex_paramrJavgbufs r-_single_tensor_rmspropr s-& 99 ! ! # # ^f%51~~~**,,+L+N ( !!T[[%5%55LL%%)EE$_`|_}}~Qx#t$ ^    1 88E86D ++E2 &&u-E%%d+D++J7J''d!e)'D  |H --h7 NN4U +$$Xxr$BHHJC//#C ''#,C((3-C a<&q)C((- HHX  ' 'c 2 JJs2#J & NN4RCN 0i&r/c ^![U5S:XagU (a [S5e[RR 5(dBU(a;[ 5m![ U!4Sj[XSS955(d[ST!S35e[U5n[R"XX#XE/5nUR5GHuunnnnnnn[[[U5n[[[U5n[[[U5n[[[U5nU(amUU/nU S:a([[[U5nURU5 U (a([[[U5nURU5 [!U/UQ76 U (a[R""U5n[RR 5(d>USR$(a*[R&"U[R("SS S 9SS 9 O[R&"US 5 U S:wa4U (a[R&"UUU S 9 O[R*"UUU S 9n[R,"UU5 [R."UUUS U- S 9 U (aw[[[U5n[R0"UUS U- 5 [R2"UUUSS 9n[R4"U5 [R&"UU5 O-[R6"U5n[R&"UU5 U S:a[[[U5n[R,"UU 5 [R8"UUU5 U(aQ[;U[R5(a2[R<"UU*5n [R&"UU 5 GM-[R&"UUU*S 9 GMGU(aR[;U[R5(a3[R>"UU*5 [R8"UUU5 GM[R8"UUUU*S 9 GM g)Nrz#_foreach ops don't support autogradc3># UHTupURRURR:H=(a URRT;v MV g7frb)r4rv).0rAr1rs r- (_multi_tensor_rmsprop..rsO A HHMMT[[-- - > !== >@sAAT)strictrkrlg?cpu)r4rmrrnrp) r;rwr<rtrur allziprr"_group_tensors_by_device_and_dtypevaluesrlistrrMr _foreach_negis_cpu _foreach_add_r? _foreach_add _foreach_mul__foreach_addcmul__foreach_lerp__foreach_addcmul_foreach_sqrt_ _foreach_sqrt_foreach_addcdiv_r% _foreach_mul _foreach_div_)"rrTrUrWrVrXrrrrrrr!r"rrYgrouped_tensorsgrouped_params_grouped_grads_grouped_square_avgs_grouped_grad_avgs_grouped_momentum_buffer_list_grouped_state_steps__grouped_params grouped_gradsgrouped_square_avgsgrouped_state_stepsstate_and_gradsgrouped_momentum_buffer_listgrouped_grad_avgsr momentum_lrrs" @r-_multi_tensor_rmsproprVs& 6{aBCC >> & & ( (Z'H'J$ v4@   ![\x[yyz{  BBBB  0DRO  " " $     ) d6lO<T&\>: "4<1EF"4<1EF ,.ABO!|/3L"?0, &&'CD$(f7I$J!&&'89 . ;? ; !..}=M ~~**,,1DQ1G1N1N   #U\\#e%DC     3Q 7 1 ##M>V % 2 2!>!  /7   QY   $T&\3E F   !2M1u9 M((#%68IQSC   %   S )%%&9:C   S ) a<+/V ;, (    .s!5-8 1ell##[s')zPAPI has changed, `state_steps` argument must contain a list of singleton tensorsNF) use_fusedz6torch.jit.script not supported with foreach optimizers) rrrrrrr!rr"rY) r<rtrurrOrrqrrrr)rrTrUrWrVrXr r!r"rrYrrrrrrrfuncs r-rrs: >> & & ( (5-8522 ^  1 e 7599))++STTuyy--//$%   !%!r/)NFFFF)__doc__typingrr<r optimizerrrrr r r r r rrrrrr__all__rrr>rgrrrrFr/r-rs^0 $ i gigV+X       Y<BJ1 LJ1 <J1fJ1F| J1 v, J1 f J1 J1 J1 J1J1J1J1J1J1 !J1"#J1$ %J1ZCW LCW <CWfCWF| CW v, CW f CW CW CW CWCWCWCWCWCW !CW"#CW$ %CWL 1GH  A LA <AfAF| A v, A f AD[AAAAA A !A" #A$%A&'A()A* +AIAr/
