@raphaelquast Thanks for your interest! We recommend you keep Spyder 3 around for production use, but with Anaconda you can easily install the Spyder 4 beta in a separate environment without affecting your Spyder 4 install, and even use the same working environment for your Consoles and code by switching it under Preferences > Python Interpereter > Use the following Python interpreter. To do so, create the environment with
conda create -n spyder-4-test python=3.6 (replace
spyder-4-test with a name of your choice if you like), then
activate the environment, and finally install Spyder 4 beta there with
conda install -c spyder-ide spyder=4.
The current release, Beta 1, has a large number of more modest new features and improvements, mostly to the Editor, Outline Explorer and Variable Explorer; however, more major new features (new debugging, new completion/introspection/debugging architecture, dark theme, etc) as well as more substantial improvements to the Outline Explorer (thanks to @jnsebgosselin ) are coming fairly soon with beta 2, or you can try them out now by
git cloneing the Spyder Github repository, making sure you have Python environment with the needed dependencies, and run
python bootstrap.py in the root of the repo to try it out.
mkllibrary used by NumPy on Windows; the error then gets triggered in Spyder when it tries to use Numpy. I've actually experienced it myself and we're waiting on the Anaconda team to hopefully fix it. For the time being, according to my testing downgrading numpy and mkl to unaffected versions (
conda install mkl=2018.0.2 numpy=1.14.3 numpy-base=1.14.3) is the only reliable solution I've found to it.
Thanks for the quick response. I'm using Windows 10.0 build 17134, and Anaconda 5.3, Python 3.7, in 64-bit - the most recent one available on anaconda.com/download.
I tried the command, and although Spyder now loads up and seems to be operating fine, a new error has popped up upon launching - "The procedure entry point mkl_blas_dgem2vu could not be located in the dynamic link library". I did notice some error string upon typing "import matplotlib", which is required for my Intro to Python course.
Thanks for your help.
conda install python=3.6) and retry if the above command didn't do it already, and you can also try
conda install anaconda=5.3.0in base or a custom environment to ensure you're using the exact tested dependency versions as the official tested Anaconda distribution, and report your results as well as exactly the steps you took (environment creation/modification, package installation/updating, conda-forge/other channels, anything else using
pip, etc) from when you install Anaconda to when the problem started occurring in the relevant thread: spyder-ide/spyder#7357
