I am new to deep learning and I have been trying to install tensorflow-gpu version in my pc in vain for the last 2 days. I avoided installing CUDA and cuDNN drivers since several forums online don't recommend it due to numerous compatibility issues. Since I was already using the conda distribution of python before, I went for the conda install -c anaconda tensorflow-gpu as written in their official website here: https://anaconda.org/anaconda/tensorflow-gpu .
However even after installing the gpu version in a fresh virtual environment (to avoid potential conflicts with pip installed libraries in the base env), tensorflow doesn't seem to even recognize my GPU for some mysterious reason.
Some of the code snippets I ran(in anaconda prompt) to understand that it wasn't recognizing my GPU:-
1.
>>>from tensorflow.python.client import device_lib
>>>print(device_lib.list_local_devices())
[name: "/device:CPU:0"
device_type: "CPU"
memory_limit: 268435456
locality {
}
incarnation: 7692219132769779763
]
As you can see it completely ignores the GPU.
2.
>>>tf.debugging.set_log_device_placement(True)
>>>a = tf.constant([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]])
2020-12-13 10:11:30.902956: I tensorflow/core/platform/cpu_feature_guard.cc:142] This
TensorFlow
binary is optimized with oneAPI Deep Neural Network Library (oneDNN)to use the following CPU
instructions in performance-critical operations: AVX AVX2
To enable them in other operations, rebuild TensorFlow with the appropriate compiler flags.
>>>b = tf.constant([[1.0, 2.0], [3.0, 4.0], [5.0, 6.0]])
>>>c = tf.matmul(a, b)
>>>print(c)
tf.Tensor(
[[22. 28.]
[49. 64.]], shape=(2, 2), dtype=float32)
Here, it was supposed to indicate that it ran with a GPU by showing Executing op MatMul in device /job:localhost/replica:0/task:0/device:GPU:0 (as written here: https://www.tensorflow.org/guide/gpu) but nothing like that is present. Also I am not sure what the message after the 2nd line means.
I have also searched for several solutions online including here but almost all of the issues are related to the first manual installation method which I haven't tried yet since everyone recommended this approach.
I don't use cmd anymore since the environment variables somehow got messed up after uninstalling tensorflow-cpu from the base env and on re-installing, it worked perfectly with anaconda prompt but not cmd. This is a separate issue (and widespread also) but I mentioned it in case that has a role to play here. I installed the gpu version in a fresh virtual environment to ensure a clean installation and as far as I understand path variables need to be set up only for manual installation of CUDA and cuDNN libraries.
The card which I use:-(which is CUDA enabled)
C:\WINDOWS\system32>wmic path win32_VideoController get name
Name
NVIDIA GeForce 940MX
Intel(R) HD Graphics 620
Tensorflow and python version I am using currently:-
>>> import tensorflow as tf
>>> tf.__version__
'2.3.0'
Python 3.8.5 (default, Sep 3 2020, 21:29:08) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on win32
Type "help", "copyright", "credits" or "license" for more information.
System information: Windows 10 Home, 64-bit operating system, x64-based processor.
Any help would be really appreciated. Thanks in advance.
conda listI saw cudatoolkit was not installed for me even though tensorflow-gpu was installed. I also saw cudnn wasn't installed. I'm trying toconda installthese now. When I didconda install cudnnit required me to downgrade from the cudatoolkit 11 I had just installed to cudatoolkit 10. Perhapsconda create -n tf-gpu tensorflow-gpuis not working well for recent releases (e.g. cudatoolkit 11). – user3731622
