Hi,

Thanks for opening the issue. The first error, looks like this issue #4. Take a look and see whether any of the solutions proposed there works for your case.

The second error, looks like something else, I'll take a look at both and I'll let you know if there is a fix.

[atomashevic]

@ibernetti63 for the first issue can you give me the output of the following code

library(transforEmotion)
library(reticulate)

transforEmotion:: setup_miniconda()

use_condaenv("transforEmotion", required = TRUE)

py_run_string("import torch; print(torch.__version__)")
py_run_string("import transformers; print(transformers.__version__)")

Also, did you try the example:

# Load data
data(neo_ipip_extraversion)

text <- neo_ipip_extraversion$friendliness[1:5]

# Cross-Encoder DistilRoBERTa
transformer_scores(
 text = text,
 classes = c(
   "friendly", "gregarious", "assertive",
   "active", "excitement", "cheerful"
 )
)

I wasn't able to reproduce both issues on a fresh install (Linux), @AlexChristensen can you try on a Windows machine?

[ibernetti63]

transforEmotionError.txt

Thank you for your quick reply. In the attached text file I have pasted the output of the commands. I used a PC with Windows 11 and R 4.4.1. Before running the commands I uninstalled miniconda to start from a clean situation.
Regards
Iacopo

I run Linux on both of my computers, so I won't be able to test Windows.

However, it seems like {pytorch} is acting up. You can try:

reticulate::conda_install(
    envname = "transforEmotion",
    packages = "torch==2.1.1",
    pip = TRUE
)

To make sure {pytorch} installs or is installed.

It would be helpful to have the output of reticulate::py_last_error() whenever there is an error that occurs

Hi @ibernetti63,

Can you test the following steps:

reticulate::miniconda_uninstall()

devtools::install_github("atomashevic/transforEmotion@cpu-only-libraries", force = TRUE)

library(transforEmotion)

setup_miniconda()

and then

# Load data
data(neo_ipip_extraversion)

text <- neo_ipip_extraversion$friendliness[1:5]

# Cross-Encoder DistilRoBERTa
transformer_scores(
 text = text,
 classes = c(
   "friendly", "gregarious", "assertive",
   "active", "excitement", "cheerful"
 )
)

Please paste any error or warning messages you get. Thanks for your patience with this issue.

Hello,

I have a similar problem.

I followed the instructions to set up Python with the transforEmotion library:

library(transforEmotion)
# Setup Python
setup_miniconda()

The installations completed without any issues, and the following packages were installed:

[1] "accelerate==0.29.3"           "llama-index==0.10.30"        
[3] "nltk==3.8.1"                  "opencv-python"                 
[5] "pandas==2.1.3"                "pypdf==4.0.1"                
[7] "pytz==2024.1"                 "qdrant-client==1.8.2"        
[9] "sentencepiece==0.2.0"         "sentence-transformers==2.7.0"
[11] "tensorflow==2.14.1"           "torch==2.1.1"                
[13] "transformers==4.35.0"         "pytubefix==6.9.2"

I then ran the manual example from the transforEmotion documentation:

library(transforEmotion)
data(neo_ipip_extraversion)
text <- neo_ipip_extraversion$friendliness[1:5] # positively worded items only
# Run transformer function
transformer_scores(
  text = text,
  classes = c(
    "friendly", "gregarious", "assertive",
    "active", "excitement", "cheerful"
  )
)

After downloading various files, the following warning appeared:

Warning: could not find TensorRT
Obtaining Scores…

Shortly after, I received this error:

R session aborted.
R encountered a fatal error. The session was terminated.

I suspect the issue may be related to CUDA. Although I haven't installed CUDA explicitly, it seems that transformers is using the CUDA-enabled version of torch. Here's what I found:

# Check torch version
py_run_string("import torch; print(torch.__version__)")
# Output:
2.1.1+cu121

# Check transformers version
py_run_string("import transformers; print(transformers.__version__)")
# Output:
4.35.0

Questions:

1. Could this issue be caused by the CUDA-enabled version of torch being used on a system without CUDA installed?
2. Should I install a non-CUDA version of torch, and if so, how can I ensure that it integrates correctly with the transforEmotion library?
3. Are there any specific steps I should take to resolve this error?

Any guidance would be greatly appreciated!

Update: Issue Persists with BART Model

Attempted BART Model:

I tried using the Facebook BART Large model for the transformer_scores function:

# Facebook BART Large
transformer_scores(
  text = text,
  classes = c(
    "friendly", "gregarious", "assertive",
    "active", "excitement", "cheerful"
  ),
  transformer = "facebook-bart"
)

---

Process:

After downloading a 1.6 GB model file, the following steps were observed:

Installing collected packages: tensorflow-cpu
Successfully installed tensorflow-cpu-2.14.1
Importing transformers and torch modules...
2024-11-19 19:36:57.807739: I tensorflow/core/platform/cpu_feature_guard.cc:182] This TensorFlow binary is optimized to use available CPU instructions in performance-critical operations.

Downloading model.safetensors:  42%|████▏     | 692M/1.63G [02:41<05:04, 3.08MB/s] 

---

Result:

The process crashed during the "Obtaining Scores" step. No additional error messages or details were provided before the crash.

Observations:

• The installation of tensorflow-cpu and the download of the model proceeded without issues.
• The crash occurred during the scoring phase, similar to the issue encountered with the default transformer model.

Request for Assistance:

1. Is the crash related to system limitations (e.g., memory or CPU)?
2. Are there specific requirements or configurations for using the facebook-bart transformer in this context?
3. Could this issue be related to a dependency mismatch or incomplete installation of supporting packages?

Any advice on debugging or resolving this issue would be highly appreciated!

[atomashevic]

Hi @snvv,

Thanks for the detailed report. Regarding the first case, the error is probably related to the CUDA version of torch. We are working on this, and it is solved in the GitHub version of the package (#22), where we have CPU versions of tensorflow and torch installed by default.

For the second case, the CPU version of tensorflow is running, which is OK, but since your R session is crashing, something else is the problem. How much free RAM do you have available before running this code? Which CPU do you have on your system?

I will try to reproduce both errors on different machines.

@ibernetti63 I haven't forgotten about your issue as well. I will investigate further and try to see if there is a fix before the release of a new version of the package.
