GPU not found error. pynvml.nvml.NVMLError_NotSupported: Not Supported

[pankhuriverma]

• CodeCarbon version: 2.3.4
• Python version: 3.10.13
• Operating System: Linux Ubuntu 22.04

I want to measure the cpu energy consumption of my python code using code carbon. My gpu version is Nvidia GeForce MX250 which does not allow energy monitoring. When I run the code I get this error because the codecarbon code is trying to find the gpu.

But when I run the same code in kaggle notebook with the same codecarbon version and python version, it is able to monitor only the cpu energy consumption when is disabled. Why is this the case?

This is the output from kaggle.

This is the code that I am running.

import tensorflow as tf

from codecarbon import EmissionsTracker

mnist = tf.keras.datasets.mnist

(x_train, y_train), (x_test, y_test) = mnist.load_data() x_train, x_test = x_train / 255.0, x_test / 255.0

model = tf.keras.models.Sequential( [ tf.keras.layers.Flatten(input_shape=(28, 28)), tf.keras.layers.Dense(128, activation="relu"), tf.keras.layers.Dropout(0.2), tf.keras.layers.Dense(10), ] )

loss_fn = tf.keras.losses.SparseCategoricalCrossentropy(from_logits=True)

model.compile(optimizer="adam", loss=loss_fn, metrics=["accuracy"])

tracker = EmissionsTracker(gpu_ids=[]) tracker.start() model.fit(x_train, y_train, epochs=10) emissions: float = tracker.stop() print(emissions)

Please help me identify what the issue is?

Hello, thanks for using codecarbon! Indeed we should check this further, there should not be any difference. Can you provide the full log of the error when you run it in your machine?

Hello @inimaz,

Thanks for your response. Below, you will find the complete error log.

Thanks! I am checking this further. Apparently gpu_ids needs to be a string with all the ids comma-separated.

gpu_ids="" will mean no gpus gpu_ids="1,3,5" will mean gpus 1, 3 and 5.

For now as a workaround for your case, you can give an empty string

tracker = EmissionsTracker(gpu_ids="")
tracker.start()

When time permits we will allow to pass an array of ints.

Hello @inimaz,

I tried it on my system but it is again giving the same error. I also think it will not work because gpu_ids only accepts a list or None. However, None is also not working in my case.

I also tried this it on kaggle but a little differently this time. As you can see in the screenshot that I have selected GPU T4 X 2 as the accelerator and passed gpu_ids = "" as input parameter. But codecarbon is still detecting the gpu. Previously when I had run the code on kaggle I had not selected any accelerator from the kaggle menu and thats why it was not detecting. If I am correct, the gpu_ids input parameter is not working as expected.

Below you will find the logs of running the code with GPU T4 X 2 accelerator and gpu_ids = "" parameter.

Logs of running the code with no accelerator and gpu_ids = "" parameter.

Logs of running the code with no accelerator and without gpu_ids = "" parameter.

In the last two cases you can see that it is giving the same output on kaggle.

[inimaz]

I see the confussion, let me explain:

• In the case of your local machine, codecarbon is detecting that there are GPUs but since you give gpu_ids="" ==> it does not count them. So it returns 0W in the total energy consumed by GPUs. See this line in the logs you provided

  [codecarbon INFO @ 19:15:15] Energy consumed for all GPUs : 0.000000 kWh. Total GPU Power : 0 W

• In the case of the kaggle notebook, codecarbon does not detect any GPU, so any id you pass in the gpu_ids will be meaningless and will not affect the output.

Hope it clarifies!

[pankhuriverma]

Hi Inimaz,

The error screenshot that I provided with 0 kWh energy consumed is from kaggle. All the screenshots with red background are from kaggle.

All the screenshots below this statement "I also tried this it on kaggle but a little differently this time." in my previous message are from Kaggle in different scenarios. This means sending gpu_ids="" on local and on kaggle is bahaving differently.

I hope you understood my issue this time.

Thanks!
