Installing tensorflow on anaconda/mac? - macos

I can not find a solution to install tensorflow on anaconda/mac.
When i try: conda install tensorflow,
I get:
UnsatisfiableError: The following specifications were found to be in conflict:
- blaze -> numba -> numpy=1.13
- tensorflow
Use "conda info " to see the dependencies for each package.
I tried reinstalling numpy, and could not find any relevant documentation.

On mac use following command:
conda install -c conda-forge tensorflow
This will install the latest Tensorflow on your system. if you wish to upgrade it to newer version then you can use the following command
conda update -f -c conda-forge tensorflow

I have had success installing tensorflow through pip...
pip install tensorflow
or, if you have all of the proper libraries...
pip install tensorflow-gpu
But if you have already removed numpy form the anaconda install, you might be in for a long day because almost all of the numeric packages require it. If the above pip install doesn't work, you might want to start from a clean anaconda install.

I have installed tensorflow using -
pip install tensorflow
Or, you can use Anaconda in following way -
Open Anaconda Navigator
On Left side go to Environments
Create a new environment (eg :- tensorflow_tf), select python 3.7
then select Not installed and Search "tensorflow"
click on tensorflow and apply

Upgrading TensorFlow Using Conda

Every time I try to upgrade tensorflow with conda, it tells me everything is updated but it hasn't done anything.
It looks like my conda is messed up because the latest TensorFlow it's showing is 2.6.0. So far the only solution I've found is a full delete and reinstall of conda.
What's wrong with conda/tensorflow?
I've used
pip install tensorflow
conda upgrade tensorflow
conda install -c conda-forge tensorflow

PyTorch dll issues for Caffe2

I am using a Windows 10 Machine and after re-installing Anaconda and all of the packages I had previously, including torchvision, torch and necessary dependencies, I am still getting this error:
OSError: [WinError 127] The specified procedure could not be found. Error loading "C:\Users\XXX\Anaconda3\envs\XXX\lib\site-packages\torch\lib\caffe2.dll" or one of its dependencies.
I am using python 3.7.9 and:
torchaudio=0.6.0=py37
torchvision=0.7.0=py37_cpu
tornado=6.0.4=py37he774522_1
traitlets=5.0.5=py_0
I've looked into it quite a bit but feel like this should be an easy solve...
I do not have CUDA and have used this:
conda install pytorch torchvision torchaudio cpuonly -c pytorch
as per instructed on the official website of pytorch
After a long time trying many things with Anaconda I decided to use bare python instead and I installed Python 3.8.6 and installed PyTorch from the link you provided and it finally worked even with CUDA support. Make sure to completely remove all Anaconda/Other Python version scripts from your path to ensure only the 3.8.6 version is used by your prompt.
I had the same problem, so I uninstalled the pytorch in my machine using
"conda uninstall pytorch torchvision torchaudio cudatoolkit=10.2 -c pytorch"
Then did a clean installation using the following
"pip install torch===1.7.0 torchvision===0.8.1 torchaudio===0.7.0 -f https://download.pytorch.org/whl/torch_stable.html"
I did not use conda for installation as it was persistently giving me the cpu version of pytorch.
I tried to install PyTorch with Anaconda and had the same error.
For me what solved the issue was to uninstall Pytorch using Pip (even though I installed it with conda) and then installing again with Pip as explains at PyTorch guide.
Uninstall:
pip uninstall torch
pip uninstall torchvision
pip uninstall torchaudio
Install:
pip3 install torch torchvision torchaudio

How to install AutoKeras on aws-ec2

I tried to install autokeras on aws ec2 (p2.xlarge) with the environment python 3.6 & tensorflow. I get following error after "pip install autokeras":
tensorflow 1.10.0 has requirement numpy<=1.14.5,>=1.13.3, but you'll have numpy 1.15.4 which is incompatible.
Installing collected packages: imageio, autokeras
Found existing installation: imageio 2.3.0
Cannot uninstall 'imageio'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
I uninstalled numpy 1.15.4 and installed numpy 1.14.5. With "conda list", I can see the numpy has the correct version.
But after "pip install autokeras" I get the same error and numpy 1.15.4 is still there.
Has anyone successfully installed autokeras on aws ec2? What shall I do to install autokeras correctly?
(Maybe the 'imageio' is the next problem?)
Thank you!
I think you need tensorflow 1.14. Here my notes for AutoKeras installation:
Autokeras Installation Notes in the Deep Learning AMI:
We launched a new deep learning AMI with ubuntu.
The deep learning AMI didn't worked using the "tensorflow + keras + py3.6" environment (so no need for a DL AMI probably, you can save space on disk using a normal clean AMI), so we managed o install autokeras doing the following:
Create a new environment with Anaconda: $ conda create -n autokeras python=3.6.
1.1. Remember that only python 3.6 is working with autokeras
Activate virtual env: It didn't work $ conda activate autokeras, but it works using $ source activate autokeras.
installation of all the packages as required by pyimagesearch.
3.1. A new problem arised here, which, long story short, was solved using the next post (note that I chenged the order, since urllib3 needs jsonschema to be installed first):
$ pip uninstall urllib3```
$ pip uninstall jsonschema
$ pip install jsonschema==2.6.0
$ pip install urllib3==1.24.1
3.2. Finally I was able to install all 3 packages:
$ pip install tensorflow # or tensorflow-gpu
$ pip install keras
$ pip install autokeras
3.3. Autokeras worked fine at this point, but it raised a warning:
>>> import autokeras
Better speed can be achieved with apex installed from https://www.github.com/nvidia/apex
So I just went to the webpage and followed the installation steps. Now it works without warnings (so far):
$ git clone https://github.com/NVIDIA/apex
$ cd apex
$ pip install -v --no-cache-dir --global-option="--pyprof" --global-option="--cpp_ext" --global-option="--cuda_ext" ./

how to install opencv and run first program in anaconda3 5.0.0 python 3.6.2 version?

I tried using
pip install opencv-python
It says to not break the installation rules and that I should use the conda command. How to install opencv and run first program on it in anaconda3 5.0.0 and python 3.6.2?
Ideall you shouldn't mix conda installed and pip installed packages - it confuses the dependencies when it comes to updates. Although you can use pip install opencv-python and opencv will work perfectly well within anaconda.
Instead you need to select opencv3 (assuming you want v3) from a specific repository
conda install -c menpo opencv3
ps. I don't know why it isn't included as standard and why have to know/search for the specific repository!

conflict while installing mayavi into anaconda

Good day,
My colleague asked my to install Anaconda and mayavi and I am novice with this topic and I decided to do the tasks on a new ubuntu installation
Here are my tasks before my issue
I fresh installed a Ubuntu 16.04
I ran all update apt-get update/upgrade
I created an user account (anna) and add it in sudo group
I loged into anna account
I downloaded Anaconda2-4.4.0-Linux-x86_64.sh for python 2.7
I installed with the command sudo bash Anaconda2-4.4.0-Linux-x86_64.sh
I installed anaconda in /opt/anaconda2 instead to the /home/anna/anaconda2 (for all user usage) and I say YES to have the line export PATH="/opt/anaconda2/bin:$PATH" in .bashrc file of anna
I run source /home/anna/.bashrc
After the anaconda installation, I could see a successful message regarding the installation
Now my colleague asked me to install mayavi and she provided me the following link mayavi
Then I simply enter the following command
conda install -c anaconda mayavi=4.5.0
And here start my problem. I can not well understand the conflict but apparently there is a conflict and I have no idea how to solve it. Here is the command and the message
anna#pc17:~$ conda install -c anaconda mayavi=4.5.0
Fetching package metadata ...........
Solving package specifications: .
UnsatisfiableError: The following specifications were found to be in conflict:
- mayavi 4.5.0* -> pyqt 4.* -> qt >=4.8.6,<5.0
- mayavi 4.5.0* -> pyqt 4.* -> sip >=4.16.4,<4.18
- navigator-updater -> pyqt >=5.6 -> qt 5.6.*
Use "conda info <package>" to see the dependencies for each package.
I have no idea what does mean the above message and how to solve me problem.
Is there depencies that I have to additionally install?
For information the above command return me this:
anna#cryospc17:~$ python --version
Python 2.7.13 :: Anaconda 4.4.0 (64-bit)
anna#cryospc17:~$ python3 --version
Python 3.5.2
Did I correctly try t install mayavi?
Thank a lot for any help you can provide me
To complete the install of mayavi, you have to first install the following depence
conda install -c anaconda vtk=6.3.0
conda install -c anaconda pyside=1.2.1
Then install mayavi
conda install -c anaconda mayavi=4.5.0
It may possible, you have to remove pyqt
conda uninstall pyqt
We finally could install anaconda and mayavi sucessfully.
I hope it help
Cheers
This might be helpfull to others. It must be anaconda for python 2.7 currently and the follows worked.
Install anaconda for python 2.7, then try the follows:
conda uninstall pyqt
conda uninstall navigator-updater
conda install pyqt=4
conda install vtk
conda install envisage
conda install pyside
conda install apptools=4.4.0
conda install mayavi
