0.4.2

• Release to CRAN after fix.

0.4.1.9000

• Returned from CRAN with note: shouldn’t link using []() or local link. Must use full URL if want to link to cran-comments.md.

0.4.1

• to CRAN after fixes.

0.4.0.9006

• Try with Solaris: pandoc (>= 2.0), qpdf ( >= 7.0);. Getting now two notes and a warrning.
• add Solaris: pkgutil -y -i qpdf, pkgutil -y -i pandoc" to SysReqs.
• use skip_on_cran() in test_r_torch_share_objects.R, test_types.R, and test-install_rtorch_dryrun.R. Causing errors in Fedora. It doesn’t want to install numpy but now errors went away in Fedora and Solaris because is nos tested on numpy.
• remove line importing numpy at the top of test file
• Instead use qpdf, pandoc (>= 2.7.2) on Solaris".
• add numpy ( >= 1.14.0) for Fedora.
• add Solaris solaris-x86-patched platform to rhub.
• Use a different SystemRequirements in DESCRIPTION: SystemRequirements: "conda (python=3.6 pytorch torchvision cpuonly matplotlib pandas -c pytorch), Python (>=3.6), pytorch (>=1.6), torchvision, numpy". It makes no difference in Fedora.
• test with fedora-clang-devel in rhub. Still throwing error ModuleNotFoundNo module named 'numpy'. failed. It seems tha Fedora cannot install numpy as painless as in Debian or Ubuntu.
• start with one of the tests in test_types.R. Put quotes at the beginning of the function parentheses in Python code.
• received message from CRAN after version 0.4.0 been accepted. Errors in Fedora and Solaris. Will use rhub to debug.

0.4.0.9005

• add unit tests for new functions
• add functions sign, abs, sqrt, floor, ceil, round, sin, cos, tan, asin, acos, atan in generics.R. Documented.

0.4.0.9004

• add file tests/testthat/rhub-tests.R that sends rTorch for testing on three different platforms. Use it as well in addition to Travis and Appveyor. Closer to CRAN tests.
• removing data.table and R6 from Imports. Not used yet.
• add more live tests. They work but torch_config does not update output after issuing a install_pytorch() command; they return the previous installed PyTorch info. The purpose of these test was initially see if the installation performed as initially planned. It works outside unit tests. But we cannot enable this test for CRAN because it will take longer time and may not work due to the PyTorch installation process. The major problem I found with these tests is that the torch_config objects do not update after issuing a new install_pytorch.
• Links to tutorials added to README.
• Remove reticulate.R from rTorch code. Some functions were previously customized to accept channel. Now the reticulate package accepts channel as a function parameter.

0.4.0.9003

• Now CRAN WinBuilder tests are passing.
• Add conda to SystemRequirements because CRAN is not passing.

0.4.0.9002

• add skip_if_no_python() so CRAN doesn’t throw error in unit test test-install_rtorch_dryrun.R
• replace function name utils.R by helper_utils.R. We also have utils.R under the R folder.

0.4.0.9001

• split test test-install_rtorch_dryrun.R in two files. The second one test-install_rtorch_parse_version.R will only perform the parsing of what is being sent to install_pytorch().
• use skip_if_no_python() in case there is no way Python is installed at the testing point.
• using package rhub for testing before releasing to CRAN.

0.4.0.9000

• use skip_if_no_torch() in tests in cases where PyTorch cannot be installed in CRAN.
• add function skip_if_no_python().
• move live torch example to a separate file.
• change \dontest to \dontrun in examples.
• create branch 0.4.0-fix_examples_problem_in_cran.

rTorch 0.4.0

• Modify tests/testthat/utils.R to include skip_on_cran()
• change version numbering so it is easier to renumber when back to CRAN for fixes.

rTorch 0.0.4.9000

• Returned from CRAN because of errors. Mainly due to lack of Python and PyTorch installation.

rTorch 0.0.4

• Release to CRAN
• Updated version of rTorch to adapt to new PyTorch versions 1.4, 1.5, 1.6.
• This rTorch release has been tested against Travis Linux, macOs, and Appveyor for Windows. All tests passed successfully. Furthermore, the package has been tested under Python 3.6, 3.7 and 3.8. A testing matrix was implemented in Travis and Appveyor to test version combinations of Python, PyTorch and R. The R versions tested were R-3.4.3, R-3.5.3, R-3.6.3, and R-4.0.2.

rTorch 0.0.3.9013

• Fixed travis.yml by bringing - PYTHON_V="3.7" PYTORCH_V="1.6" near env: metrix. Maybe some space or alignment was preventing ennvronment variables being passed to Travis containers.
• Travis test passing with Python 3.8 in Linux and macOS. Environment variables are not being passed.
• add function is_rtorch_env_name() and env_name object to torch_config() to live unit test install_pytorch()
• add function install_pytorch() to vignette
• add parameter python_version to function conda_install()
• add backticks to roxygen text since now we are using Markdown in Roxygen: list(markdown = TRUE)
• new pkgdown section for Installation. Add two logical functions
• use markdown in roxygen help text
• Travis test PyTorch 1.5 in R-4.0.2 for Linux and macOS with variable shortened.
• Appveyor test PyTorch 1.6 in R-4.0.2 for Windows.
• New Appveyor test with PyTorch 1.5 in R-4.0.2 for Windows. Failing. Definitely PyTorch 1.5 failing in most of the tests.
• Shorten the variable names PYTORCH_VERSION and PYTHON_VERSION in Travis.
• Appveyor test PyTorch 1.6 in R-4.0.2 for Windows. Passed.
• Appveyor test PyTorch 1.5 in R-4.0.2 for Windows. Failed.
• Travis test PyTorch 1.5 in R-4.0.2 for Linux and macOS
• change logical and, or and not to be boolean or uint8 as their inputs.
• do the same for equal and not equal.
• add a parameter to force to return boolean values instead of uint8 types. Currently, AND (“!”) and OR (“|”) return booleans while NOT and others don’t; they return uint8. We should fix this lack of consistency.
• testing on macOS in Travis.
• add condition when PyTorch is 1.1 or lower to compare against uint8. Newer PyTorch versions make the conversion of the comparison and return boolean values. In 1.1 they return uint8.
• modify functions torch$eq() and torch$ne() to validate boolean inputs.
• modify tests for eq() and ne() in PyTorch 1.1. They return tensor(True, dtype=torch.bool) or tensor(False, dtype=torch.bool).
• add more examples in generics.R and properties.R

rTorch 0.0.3.9012

• Finding a problem when using PyTorch 1.1 in logical operations.
• logical generic functions should return uint8 types as original PyTorch functions in generics.R.
• new unit tests for torch$all, torch$any and some generic logicals in test-tensor_comparison.R.
• switch to a couple of Travis and Appveyor tests to save time.
• modify generic !.torch.Tensor to return boolean if input is boolean, otherwise return opriginal type. Fix tests in test_generics.R and test_numpy_logical.R.
• tests for 4 PyTorch versions in R-4.0.2 and Python 3.7,

rTorch 0.0.3.9011

• Because PyTorch 1.1 and 1.2 are failing on Python 3.8, we could install a custom pytorch with install_pytorch(conda_python_version = "3.8", version = "1.2"). Tests failed. But not because of PyTorch but conflict during the conda installation.
• Other custom pytorch with install_pytorch(conda_python_version = "3.8", version = "1.4") with tests passed.
• add numpy version to printout of rtorch_config().
• perform rebase to get rid off wrong settings for matrix jobs in travis. Keep only those settings that worked.
• maybe a good idea to remove tests with Python 3.8 because they fail with all PyTorch versions.
• add environment variable PYTHON_VERSION to conda in build_script of appveyor. Twelve (12) passed.
• Duplicate matrix for Travis tests. Now we have tests for Python 3.6 and Python 3.7, and 3.8 for only PyTorch 1.6, a total of 36 tests. All passed.
• Duplicate matrix for Appveyor tests. Now we have tests for Python 3.6 and Python 3.7, a total of 36 tests. All passed.
• Testing develop branch with Travis and Appveyor. All tests passed.

• With PyTorch 1.6 we are getting the warning extract syntaxsys:1: UserWarning: The given NumPy array is not writeable, and PyTorch does not support non-writeable tensors. This means you can write to the underlying (supposedly non-writeable) NumPy array using the tensor. You may want to copy the array to protect its data or make it writeable before converting it to a tensor. This type of warning will be suppressed for the rest of this program. (Triggered internally at /opt/conda/conda-bld/pytorch_1595629417679/work/torch/csrc/utils/tensor_numpy.cpp:141.).
