Hi 

Have you tried this one?

You can easily install this beta if you use Anaconda by running:

conda update qt pyqt
conda install -c spyder-ide spyder=4.0.0b6

Or you can use pip with this command:

pip install --pre -U spyder

From what I've seen it is not recommended to use pip with an anaconda installation as it breaks the conda installation and spyder.

You should start with a clean Anaconda installation.

Right click the Start Button, go to Apps and Features and Uninstall Anaconda.

Then go to C:\Users\shraddha.sarode and delete all the subfolders beginning with a . such as

.anaconda

.conda

.config

.ipynb_checkpoints

.ipython

.jupyter

.spyder-py3

.spyder-py3-dev

.vscode

Next restart your computer. Then install Anaconda using the 2020-02 installer which includes Spyder 4.0.1 and all its required dependencies.
