Pull Request resolved: https://github.com/pytorch/pytorch/pull/63068
The caffe2 core.Net constructor can accept a caffe2_pb2.NetDef proto, but it always creates a copy. This is wasteful when we can prove that the proto being passed to it will not be used anywhere else. So we add an "inplace" argument to the `core.Net` constructor that allows clients to give away ownership of the passed proto without copying. We default this argument to `False`, ensuring that behavior does not change unless explicitly requested.
Test Plan: Let CI run.

`Net.AddExternalInput` should raise if there are duplicate names. The previous code would only raise if the addition of duplicates was in separate calls, but not if it was in the same call.
Test Plan:
Added two new regression tests
```
✓ Pass: caffe2/caffe2/python:core_test - testSetInputRecordWithBlobs (caffe2.caffe2.python.core_test.TestExternalInputs) (9.622)
✓ Pass: caffe2/caffe2/python:core_test - testAddExternalInputShouldRaiseIfDuplicate (caffe2.caffe2.python.core_test.TestExternalInputs) (9.639)
✓ Pass: caffe2/caffe2/python:core_test - testSetInputRecordWithoutBlobs (caffe2.caffe2.python.core_test.TestExternalInputs) (9.883)
✓ Pass: caffe2/caffe2/python:core_test - testAddExternalInputShouldRaiseIfDuplicateInSameCall (caffe2.caffe2.python.core_test.TestExternalInputs) (10.153)

Pull Request resolved: https://github.com/pytorch/pytorch/pull/10739
I wanted to assert that the blobs in the workspace of the new session after loading checkpoint are exactly the same as the blobs in the workspace of the old session before saving to a checkpoint.
But I found that when calling `task.get_step()`, a dummy task output blob, `task:output/ConstIntFill:0`, is added. Also a dummy net `task:output` was also added along with it. See https://fburl.com/937lf2yk
This makes it hard to assert "Equal", forcing me to assert "LessThan" or "GreaterThan".
This adding a dummy TaskOutput when user specifies no TaskOutput is a hack.
The reason for this is that ZMQ socket can't send empty blob list.
As a result, if the Task on the Worker had no output,
The master would never stop waiting and hang forever. See https://fburl.com/rd7fhy6p and imagine `socket.recv(net, 0)`.
TaskOuput is at user layer. The hack shouldn't be exposed to user layer, polluting user workspaces.
Instead, we should move the creating of the dummy blob to some deeper layer,
and remove the dummy blob in the workspace afterwards to avoid polluting user workspaces.
After this change, the workaround becomes totally transparent and no side-effect to users.

* [CUDA9] Upgrade - fbcode
CUDA9 upgrade diff D5654023 has been out for a while thanks to Pieter. But with time growing it's becoming quite hard to rebase, because of the symlinks and auto-generated build/config files in tp2. Break D5654023 into two diffs, one touching tp2 config files, and another one touching fbcode TARGETS file (adding nvcc flag). These two should be a bit easier to rebase (for detailed procedure see "Test Plan").
This diff can only be committed if:
1. CUDA 9 rpm is rolled out fleet-wide (TBD)
2. NVidia driver 390.40 is rolled out fleet-wide (done)
3. Upgrade CUDA 9.1, cudnn 7.1, nccl 2.1 (done)
4. Make sure all dependents are built (done)
5. Test all C2 operators, PyTorch (see test plan)

* Caffe2: avoid static initialization order fiasco for CAFFE_ENFORCE
CAFFE_ENFORCE uses strack trace fetcher. Which is currently a
global static variable. If at static initialization time CAFFE_ENFORCE
is used, this is a SIOF. Recently CAFFE_ENFORCE was added into init
functions registration, so we started to see this.

fetcher was not registered yet, it will just use a dummy one.

* Implementation of composite learning rate policy
In many state-of-the-arts deep learning works, people use a simple trick to
schedule the learning rate: use a fixed learning rate until error plateaus
and then switch to a different fixed learning rate, and so on. In this diff,
we implemented a simple version of the composite learning rate. The user gives
a set of learning rates policies and corresponding iteration nums, and the
optimizer will change the learning rate policy based on the number of iterations so far.
For example, the user give two learning rate policies, one is FixedLearningRate
and PolyLearningRate, with an iteration number of 1k. Then the first 1k iteration,
we use FixedLearningRate. For the following iterations, we use PolyLearningRate.
* Split two use cases of CachedReader into two classes, DBFileReader and CachedReader

* Add barrier net that runs before training nets - attempt #2

Removed explicit data_parallel_model.py.synchronize call in holmes workflow.
This change was landed previously but caused errors for some EDPM workflows - See https://fb.facebook.com/groups/1426530000692545/permalink/1906766366002237/ - because EDPM assumes any call to CreateOrCloneCommonWorld and Gloo ops are wrapped in exception handlers but in this case exception thrown in the barrier init net is not handled.
To address this issue, we add _CreateOrCloneCommonWorld to the param_init_net instead of a new barrier init net. Since errors for param_init_net run is handled gracefully and re-rendezvous, it should fixes the problem.

* [pos_disc, fbcode] Implement unjoined lr loss
As explained in https://our.intern.facebook.com/intern/wiki/Model_Based_Calibration/, when the dataset is an joined data set, where labels might change later, we need to use unjoined logloss.
The implementation is almost the same as in Sigrid (https://fburl.com/1trngsls), where
loss = y (log(p) - log(1-p)) + (1-y)(log(1-p)) = xy - (1-y)x - (1-y)log(1+exp(-x))
For x < 0, to ensure stability and avoid overflow, we reformulate the above exp as
loss = xy - (1-y)x - (1-y)x + (1-y)log(1+exp(x)) = xy + (1-y)log(1+exp(x))
Then the final expression becomes
loss = xy + (y - 1) x (x >= 0) - (1 - y) log(1 + exp(x - 2 x (x >= 0)))
where y is the true label, x is the dot product and p = logistic(x).
This kind of implementation is align with the current implementation of the original cross entropy in
https://phabricator.intern.facebook.com/diffusion/FBS/browse/master/fbcode/caffe2/caffe2/operators/cross_entropy_op.cc;0bae3b5d0f825897c5e0dd0ff10f489d7271bf25$7-13

* [Easy] Add cast op before computing norm in diagnose options

* Introduce a new caching device allocator
`cudaMalloc` and `cudaFree` calls are slow, and become slower the
more GPUs there are. Essentially, they grab a host-wide (not device-wide) lock
because GPU memory is transparently shared across all GPUs. Normally, this
isn't much of a concern since workloads allocate memory upfront, and reuse it
during later computation.
However, under some computation models (specifically, memory conserving
approaches like checkpoint-and-recompute, see
https://medium.com/@yaroslavvb/fitting-larger-networks-into-memory-583e3c758ff9)
this assumption is no longer true. In these situations, `cudaMalloc` and
`cudaFree` are common and frequent. Furthermore, in data parallel contexts,
these calls happen at nearly the same time from all GPUs worsening lock
contention.
A common solution to this problem is to add a custom allocator. In fact,
nVIDIA provides one out of the box: CUB, which Caffe2 already supports.
Unfortunately, the CUB allocator suffers from very high fragmentation. This is
primarily because it is a "buddy" allocator which neither splits nor merges
free cached blocks. Study
https://github.com/NVlabs/cub/blob/1.8.0/cub/util_allocator.cuh#L357 if you
want to convince yourself.
This diff adapts a caching allocator from the Torch codebase

which does splitting and merging and ends up working really well, at least for
workloads like the checkpoint-and-recompute computation models noted above.
I simplified the implementation a little bit, made it a bit more C++-like. I
also removed a bunch of stream synchronization primitives for this diff. I
plan to add them back in subsequent diffs.
* Report reader progress in fblearner workflows
Integrate with fblearner progress reporting API and add support to report training progress from reader nodes.
If reader is constructed with batch limits, report based on finished batch vs total batch. The finished batch may be more than total batch because we evaludate if we should stop processing everytime we dequeue a split.
If no limit for the reader, report based on finished splits (Hive files) vs total splits. This is fairly accurate.
* [GanH][Diagnose]: fix plotting

* Make CompositeReader stops as soon as one reader finishes
Previously, CompositeReader calls all readers before stopping. It results in flaky test since the last batch may be read by different threads; resulting in dropped data.

Thanks for finding this @stzpz and @wangyanghan. Looks like NHWC is more

will soon become important.

* std::round compat
This is required to support placeholder/decorator ops which does not have operator schema. Note that the change is made in such a way that it is a no-op if placeholder Ops are not used.
Changes:
1. Since the placeholder ops always run on CPU, added a utility to infer placeholder ops blob devices.
2. Placeholder op's input/output blobs should be on CPU as well. This change takes care of dealing with output blobs - i.e. use blobs on CPU.
3. Added a Unit test - test_inject_copy_placeholder_ops
Changes:
=======
1. Added device inference functions for Concat and Split Ops.
2. Added a unit test to validate the change. See, test_device_inference_function in core_test.py
3. Fixed some formatting.
Summary: Currently, the device_option equality is done in a specialized private function. Ideally, we should be able to test the equality from other places in the code and have a more detailed check for the equality.

Summary: If a blob is copy from device A to device B in the init_net, and then is used as an external_input in the train_net, we want the train_net to correctly use the blob already on device B instead of copying it over and over again.

Summary: fixing the case where the init net will initialize same blob twice. I made an exception by allowing inplace blob among ops if the blob keeps on the same device. This should fix this problem in a generalized way as most of our training is only on CPU now.

Summary:
Last time I used uuid filled into OperatorDef. And operator_tracebacks was populated using traceback.extract_stack. There were several issues with this approach:
1. A random field in OperatorDef breaks workflows relying on memoization, i.e. when computation is skipped based on already computed result before.
2. Adding one more field revealed RNNs being non forward compatible wrt to new fields in there. prototxt format seems to not allow forward compatibility (thanks jamesr66a for the investigation!). For RNNs we need to swtich them to a more resilient approach. azzolini's proposed change to OperatorDef / NetDef would allow that by just nesting NetDef dirrectly inside OperatorDef without need for extra serialization.
3. traceback.extract_stack is very slow when executable is on a remote filesystem. It does one or more os.stat for each frame on the stack. For some cases it ended up being up to 15 extra minutes on model construction.
In this diff I use a different approach which should fix all those problems above.
1.2. are solved by not adding a new field at all. Instead I report operator idx wrt to a net it runs in. Thanks akyrola and dzhulgakov for the idea. Downside here is that operator list manipulation breaks the logic and separately created ops are not covered at all.
3. I solved this by operating on raw frames without using traceback and inspect modules which end up doing a lot of file system calls. See function extract_stacktace in core.py with additional comments.

Summary:
a few issues:
1. Randomization hurts memoization
1. Even if we make it non random, then we can get key colisions when loading it back.
2. RNNs use prototxt for step net and apparently its not forward compatible like normal protobuf is
I am thinking of a better less invasive solution now.

Summary:
This diff plan to attack the problem where we want to just annotate device option for operators and leave Caffe2 to help us inject cross device copy functions. This feature would be useful for mixed device training and multi device training with several nets, where previously we do the heavy lifting of adding copy functions ourselves.
Ideally, this feature will happen like this:
//construct your nets first
core.InjectDeviceCopyAmongNets([train_init, train_net, ...])
My ideas are written in comments. I will update them here as well later.
