      E outra coisa, apos ter feito a data augmentation for base_treinamento:

      base_treinamento = base_treinamento.map(lambda imagens, labels: (pre_processamento(imagens), labels))

      Se faço o codigo abaixo para saber o novo numero de imagens nele contido, está me retornando -1:

      tamanho_treinamento = base_treinamento.cardinality().numpy()
      tamanho_treinamento

        kkkkkk

        professor, se poder responder a uma das minhas outras perguntas, que aproveito colocar desde já por aqui sobre os algos de matching.

         

        Professor, estou tentar localizar um curso que ensine diferentes algo para fazer o MATCHING mas não encontro.

        podes, por favor me indicar um curso das trilhas que ensina isso? No pior de caso, um link exterior onde posso buscar conhecimento em relação ao isso.

         

        Atentamente

          Foram muitas trocas de msg e uma chamada, posto aqui 2 minhas e 2 delas:

          Olá!
          Eu tinha escolhido a opção gratuita de utilizar o Sagemaker com um utilizador para um domínio.
          Pensei que não me iam cobrar e depois vi no meu cartão que me foi debitado 28$ por um pagamento da Amazon.
          Na verdade, estou muito surpreendido, porque me cobrou todo o dinheiro da minha conta bancária, embora eu seja apenas um estudante universitário.
          Eu queria utilizar AWS Sagemaker para os meus projectos pessoais.
          Por favor, pode cancelar esta transacção e colocar-me de volta na opção gratuita?

          RESPOSTA AWS:

          Hi there, I am following up on our recent phone conversation.

          As confirmed, the charges are for Sagemaker in the EU (Paris) region and accrued as the specifications of the Free Tier offer were exceeded.

          For details on what AWS services are covered by the AWS Free Tier, as well as their specifications, please see: https://aws.amazon.com/free/?all-free-tier.sort-by=item.additionalFields.SortRank&all-free-tier.sort-order=asc

          In order for me to assist with a billing adjustment, we require the chargeable services to be deleted:

          1) Navigate to the SageMaker Console by clicking this link: https://eu-west-3.console.aws.amazon.com/sagemaker/home?region=eu-west-3#/landing

          2) Select the following resources from the menu on the left hand side and delete them. The endpoint. Note: This also deletes the ML compute instance or instances. The endpoint configuration. The model. The notebook instance. Note: You will need to stop the instance before deleting it.

          3) Open the Amazon S3 console at https://console.aws.amazon.com/s3/ and delete the bucket that you created for storing model artifacts and the training dataset.

          4) Open the IAM console at https://console.aws.amazon.com/iam/ and delete the IAM role. If you created permission policies, you can delete them, too.

          5) Open the Amazon CloudWatch console at https://console.aws.amazon.com/cloudwatch/ and delete all of the log groups that have names starting with /aws/sagemaker/. Reference: https://docs.aws.amazon.com/sagemaker/latest/dg/ex1-cleanup For more information on how to stop your training jobs please see: https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_StopTrainingJob.html

          Kindly let me know once the above has been actioned, and I will be happy to further assist. Appreciate your teamwork and understanding. Apologies for any inconvenience caused. We value your feedback.

          MINHA MSG

          Hi, I want just to let you know that the above/below has been actioned as recommended. I m looking for to know you next step on how to help me retrieve my fund that has been debited on my account and also how i can use sagemaker with small ressources ou service for learning and training my small models as UNIVERSITY STUDENT. best regards, Ebenezer

          THEIR ANSWER

          Thanks for your cooperation and quick response.

          As a once off exception, we’ve issued a refund of $28.15 USD. The refund is returned to the card or bank account that you used to pay the bill.

          The refund can take up to seven working days to appear. We can’t tell you the date that you can expect the refund to appear, as processing times vary by bank. You can confirm the refund in your console: https://console.aws.amazon.com/billing/home#/paymenthistory

          Additionally, we’ve approved a credit of $58.00 USD and have applied it to your AWS account. The credit automatically absorbs any service charges that it applies to. Because the credit reduces your service charges, you will see an update to the total tax amount.

                Sim dei conta só agora que havias colocado – o no inicio de cada seção visto que eu já estava avançado com as aulas.

                Si fiz a reclamação, mandaram me deletar tudo e devolveram me os valores.

                Deram mais mais um credito de 58$ que posso usar por enquanto.

                São as vezes bondosos esses gajos

                kkkk

                Participant

                  So para consolidar a minha ultima pergunta, o professor confirma que todos os cursos de vossos trilhas, os algo para series temporaias são bem Deepar et Prophet por favor? Ou ainda tem outros? Se sim em que curso por favor?

                  Participant

                    Professor, então quando se fala de Clustering, é basicamente em relação ao agrupamento de k-means e outros que já vi neste curso?

                    • Agrupamento – k-means, agrupamento hierárquico e DBSCAN
                      – Tópicos complementares – redução de dimensionalidade com PCA, KernelPCA e LDA, deteção de outliers, aprendizagem por reforço.

                    OU ainda tem mais outras coisas?

                      Professor, depois de ter instanciado ckpt, ckpt_manager, Dcnn da classe DCNN, quando faço ckpt.restore(ckpt_manager.latest_checkpoint)

                      Recebo de facto a confirmacao de que o ultimo checkpoint foi restaurado e me retorna até:

                      <tensorflow.python.training.tracking.util.CheckpointLoadStatus at 0x7fbca3494b50>

                      Agora como quero utilizar o restaurado para não fazer mais o fit, como procido para proxima etapa para usar history e suas metricas para poder fazer graficos com eles conforme fizemos em aula?

                      Repito que não pretendo executar o codigo abaixo para não fazer mais o fit do modelo vsito que que quero usar o ultimo checkpoint restaurado:

                      class MyCustomCallBack(tf.keras.callbacks.Callback):
                      def on_epoch_end(self, epoch, logs=None):
                      ckpt_manager.save()
                      print(“Checkpoint savet at {}”.format(checkpoint_path))

                      history = Dcnn.fit(train_dataset,
                      epochs=NB_EPOCHS,
                      #steps_per_epoch = 100,
                      callbacks=[MyCustomCallBack()])

                        Fiz isso mas dei conta que não suporta mesmo bem outras linguas viston que quando fiz:

                        print(tokenizer.vocab)

                        Elle me retornou 119547 palvras mas só ouvias menos de 10 em francês ou português.

                        Gostaria muito que os cursos fossem actualisados para ajudar os novos alunos que estão se inscrevendo.

                        Alguém disse me para pesquisar: camemBERT, não sei se voces já ouviram falar.
