Installation on windows 10 failed

[Kim Tang]

Hello,

I followed the instruction and tried to install from the requirement.txt in python folder. But unfortunately I got the following error message. Can you please help to resolve?

Thanks,
Kim

(drlnd) deep-reinforcement-learning\python

pip install .

Hi Kimtang,

i have faced similar problem before and as i remember the problem was having higher version than the needed in the requirement.txt, so the solution either to install the elder version or change the requirement with the new version,
for me i have checked the difference between the two versions firstly before changing the requirement file

Yes, pip has actually problem to install pytorch. So I deleted the line from requirements.txt and install it from anaconda.

Dont really like to use two installation tool (anaconda and pip).

Looks like it is really torch not pytorch. But installing it from pip or conda is not possible in windows.

I use windows 10 and I had the same problem. In my case, I installed pytorch via conda and removed it from requeriments.txt.

Steps:

On Windows:

1. Open deep-reinforcement-learning\python\requirements.txt
2. Remove the line torch==0.4.0

On Anaconda:

3. conda install pytorch=0.4.0 -c pytorch
4. cd deep-reinforcement-learning/python
5. pip install .
