" Wednesday, a step that gives the court jurisdiction over alleged crimes in Palestinian territories. The"
" formal accession was marked with a ceremony at The Hague, in the Netherlands, where the court is based."
" The Palestinians signed the ICC's founding Rome Statute in January, when they also accepted its"
' jurisdiction over alleged crimes committed "in the occupied Palestinian territory, including East'
' Jerusalem, since June 13, 2014." Later that month, the ICC opened a preliminary examination into the'
" situation in Palestinian territories, paving the way for possible war crimes investigations against"
" Israelis. As members of the court, Palestinians may be subject to counter-charges as well. Israel and"
" the United States, neither of which is an ICC member, opposed the Palestinians' efforts to join the"
" body. But Palestinian Foreign Minister Riad al-Malki, speaking at Wednesday's ceremony, said it was a"
' move toward greater justice. "As Palestine formally becomes a State Party to the Rome Statute today, the'
' world is also a step closer to ending a long era of impunity and injustice," he said, according to an'
' ICC news release. "Indeed, today brings us closer to our shared goals of justice and peace." Judge'
" Kuniko Ozaki, a vice president of the ICC, said acceding to the treaty was just the first step for the"
' Palestinians. "As the Rome Statute today enters into force for the State of Palestine, Palestine'
" acquires all the rights as well as responsibilities that come with being a State Party to the Statute."
' These are substantive commitments, which cannot be taken lightly," she said. Rights group Human Rights'
' Watch welcomed the development. "Governments seeking to penalize Palestine for joining the ICC should'
" immediately end their pressure, and countries that support universal acceptance of the court's treaty"
' should speak out to welcome its membership," said Balkees Jarrah, international justice counsel for the'
" group. \"What's objectionable is the attempts to undermine international justice, not Palestine's"
' decision to join a treaty to which over 100 countries around the world are members." In January, when'
" the preliminary ICC examination was opened, Israeli Prime Minister Benjamin Netanyahu described it as an"
' outrage, saying the court was overstepping its boundaries. The United States also said it "strongly"'
" disagreed with the court's decision. \"As we have said repeatedly, we do not believe that Palestine is a"
' state and therefore we do not believe that it is eligible to join the ICC," the State Department said in'
' a statement. It urged the warring sides to resolve their differences through direct negotiations. "We'
' will continue to oppose actions against Israel at the ICC as counterproductive to the cause of peace,"'
" it said. But the ICC begs to differ with the definition of a state for its purposes and refers to the"
' territories as "Palestine." While a preliminary examination is not a formal investigation, it allows the'
" court to review evidence and determine whether to investigate suspects on both sides. Prosecutor Fatou"
' Bensouda said her office would "conduct its analysis in full independence and impartiality." The war'
" between Israel and Hamas militants in Gaza last summer left more than 2,000 people dead. The inquiry"
" will include alleged war crimes committed since June. The International Criminal Court was set up in"
" 2002 to prosecute genocide, crimes against humanity and war crimes. CNN's Vasco Cotovio, Kareem Khadder"
" and Faith Karimi contributed to this report."

" breach of the due process of law. Therefore, his police custody and subsequent judicial custody"
" in the case were all illegal. Kapoor has urged the High Court to quash and set aside the special"
" court's order dated August 14. As per his plea, in August this year, the CBI had moved two"
" applications before the special court, one seeking permission to arrest Kapoor, who was already"
" in judicial custody at the time in another case, and the other, seeking his police custody."
" While the special court refused to grant permission to the CBI to arrest Kapoor, it granted the"

" application for his arrest, the CBI had not followed the process of issuing him a notice under"

" was already in judicial custody in another case and was not a free man the procedure mandated"
" under Section 41 of the CrPC need not have been adhered to as far as issuing a prior notice of"
" appearance was concerned. ADVERTISING It had also said that case records showed that the"
" investigating officer had taken an approval from a managing director of Yes Bank before"
" beginning the proceedings against Kapoor and such a permission was a valid sanction. However,"

" set aside. The law mandated that if initial action was not in consonance with legal procedures,"
" then all subsequent actions must be held as illegal, he said, urging the High Court to declare"
" the CBI remand and custody and all subsequent proceedings including the further custody as"
" illegal and void ab-initio. In a separate plea before the High Court, Kapoor's daughter Rakhee"

🤗 Transformers: State of the Art NLP
🤗 Transformers provides thousands of pretrained models to perform tasks on texts such as classification, information extraction,
question answering, summarization, translation, text generation and more in over 100 languages.
Its aim is to make cutting-edge NLP easier to use for everyone.
🤗 Transformers provides APIs to quickly download and use those pretrained models on a given text, fine-tune them on your own datasets and
then share them with the community on our model hub. At the same time, each python module defining an architecture is fully standalone and
can be modified to enable quick research experiments.
Why should I use transformers?
1. Easy-to-use state-of-the-art models:
- High performance on NLU and NLG tasks.
- Low barrier to entry for educators and practitioners.
- Few user-facing abstractions with just three classes to learn.
- A unified API for using all our pretrained models.
- Lower compute costs, smaller carbon footprint:
2. Researchers can share trained models instead of always retraining.
- Practitioners can reduce compute time and production costs.
- Dozens of architectures with over 10,000 pretrained models, some in more than 100 languages.
3. Choose the right framework for every part of a model's lifetime:
- Train state-of-the-art models in 3 lines of code.
- Move a single model between TF2.0/PyTorch frameworks at will.
- Seamlessly pick the right framework for training, evaluation and production.
4. Easily customize a model or an example to your needs:
- We provide examples for each architecture to reproduce the results published by its original authors.
- Model internals are exposed as consistently as possible.
- Model files can be used independently of the library for quick experiments.
🤗 Transformers is backed by the three most popular deep learning libraries — Jax, PyTorch and TensorFlow — with a seamless integration
between them. It's straightforward to train your models with one before loading them for inference with the other.

# 2 - To reduce the chance of false positives (i.e. passing when it should be failing), we run the check
# multiple times with random inputs, and it has to pass with all of them.
# NOTE: because of 2), there is some chance of false positives in this test.

Welcome to tests_fetcher V2.
This util is designed to fetch tests to run on a PR so that only the tests impacted by the modifications are run, and
when too many models are being impacted, only run the tests of a subset of core models. It works like this.
Stage 1: Identify the modified files. This takes all the files from the branching point to the current commit (so
all modifications in a PR, not just the last commit) but excludes modifications that are on docstrings or comments
only.
Stage 2: Extract the tests to run. This is done by looking at the imports in each module and test file: if module A
imports module B, then changing module B impacts module A, so the tests using module A should be run. We thus get the
dependencies of each model and then recursively builds the 'reverse' map of dependencies to get all modules and tests
impacted by a given file. We then only keep the tests (and only the code models tests if there are too many modules).
Caveats:
- This module only filters tests by files (not individual tests) so it's better to have tests for different things
in different files.
- This module assumes inits are just importing things, not really building objects, so it's better to structure
them this way and move objects building in separate submodules.
