## Information

I am using `run_seq2seq.py` in `transformers/examples/seq2seq`

The problem arises when using:
* the official example scripts: 
when I run the following:

```
python run_seq2seq.py \
    --model_name_or_path t5-small \
    --do_train \
    --do_eval \
    --task summarization \
    --train_file train.csv \
    --validation_file test.csv \
    --output_dir output \
    --overwrite_output_dir \
    --per_device_train_batch_size=4 \
    --per_device_eval_batch_size=4 \
    --predict_with_generate \
    --max_train_samples 500 \
    --max_val_samples 500
```

I get the following error:

```
Traceback (most recent call last):
  File "run_seq2seq.py", line 645, in <module>
    main()
  File "run_seq2seq.py", line 518, in main
    pad_to_multiple_of=8 if training_args.fp16 else None,
TypeError: __init__() got an unexpected keyword argument 'model'
```
The tasks I am working on is:
* my own task or dataset:

I take the examples provided in the README file for the custom CSV file. Specifically, I have two files `train.csv` and `test.csv` in the same directory as `run_seq2seq.py` with the following content:

```
text,summary
"I'm sitting here in a boring room. It's just another rainy Sunday afternoon. I'm wasting my time I got nothing to do. I'm hanging around I'm waiting for you. But nothing ever happens. And I wonder","I'm sitting in a room where I'm waiting for something to happen"
"I see trees so green, red roses too. I see them bloom for me and you. And I think to myself what a wonderful world. I see skies so blue and clouds so white. The bright blessed day, the dark sacred night. And I think to myself what a wonderful world.","I'm a gardener and I'm a big fan of flowers."
"Christmas time is here. Happiness and cheer. Fun for all that children call. Their favorite time of the year. Snowflakes in the air. Carols everywhere. Olden times and ancient rhymes. Of love and dreams to share","It's that time of year again."
```

## To reproduce

Steps to reproduce the behavior:

1. I copy and paste the file `run_seq2seq.py` located [here](https://github.com/huggingface/transformers/blob/master/examples/seq2seq/run_seq2seq.py) into a directory.
2. I create two files named `train.csv` and `test.csv` in the same directory the file `run_seq2seq.py` is located.
3. I run the command provided above.

Here's the full terminal output:

All model checkpoint weights were used when initializing T5ForConditionalGeneration.

All the weights of T5ForConditionalGeneration were initialized from the model checkpoint at t5-small.
If your task is similar to the task the model of the checkpoint was trained on, you can already use T5ForConditionalGeneration for predictions without further training.

I have the same exact problem. Even if you skip that part, it keeps happening in other parts of the code. It seems that file hasn't been updated with the last changes.<|||||>any solution for this? issue persists<|||||>This is because of the old version of `transformers`, upgrading to master should resolve this issue. Also always install transformers from source to use examples.<|||||>I had the same issue. Upgrading to master solved the issue. 

I have a somewhat related question: 
Currently, the metrics are logged at the end of the training.
The output right now looks like: 
```

```
I was wondering if  there an easier way of getting metrics (say rouge score/loss) for each epoch so that we can see how the training is going and plot the loss? One solution that I could think of was writing a custom callback function with `on_epoch_end`. Just wondering if there's an easier solution?
<|||||>There is,
you could set the `evaluation_strategy`  and `logging_strategy` argument to `epoch`, which will tell the trainer to evaluate and log after each epoch. If it doesn't feel free to createe another issue.
